PD-9782A LSO SERIES HYBRID-HIGH RELIABILITY RADIATION HARDENED DC-DC CONVERTER 28V Input, Single/Dual Output Description The LSO Series of DC-DC converters are, high reliability devices designed for hostile radiation hardened environments. The design is based on the heritage-rich LS Series with enhanced functional performance and an inclusion of an output overvoltage protection. The LSO Series provide up to 3 watts output power, small size, low weight, integrated EMI filtering and a high tolerance to environmental stresses such as radiation, temperature extremes, mechanical shock, and vibration. All components are fully de-rated to meet the requirements of MIL-STD-547, MIL-STD-975 and NASA EEE-INST-2. Extensive documentation including, thermal analysis, stress analysis and reliability predictions are available. The LSO Series of converters incorporate a fixed frequency single forward topology with magnetic feedback and an internal EMI filter. These converters are capable of meeting the conducted emissions requirements of MIL-STD-46C without any additional components. All models include an external inhibit port and have an adjustable output voltage. The converters are overload, short circuit and output over-voltage protected. They are enclosed in a hermetic 3.5" x 2.5" x.475" H steel package and weigh less than 25 grams. The package utilizes rugged ceramic feed-through copper core pins and is sealed using parallel seam welding. Manufactured in a facility fully qualified to MIL-PRF-38534, these converters are fabricated utilizing DLA qualified processes. For available screening options, refer to device screening table in the data sheet. Variations in electrical specifications and screening to meet custom requirements can be accommodated.

Circuit Description The LSO Series converters utilize a single-ended forward topology with resonant reset. The nominal switching frequency is 5kHz. Electrical isolation and tight output regulation are achieved through the use of a magnetically coupled feedback. Voltage feed-forward with duty factor limiting provides high line rejection. An internal EMI filter allows the converter to meet the conducted emissions requirements of MIL-STD-46C on the input power leads. Functional Notes Input Current Telemetry: The LSO Series single and dual output models also feature an input current telemetry with a magnitude of to 3.3V full scale. The voltage signal at this pin (Pin 7) with respect to Output Return (Pin 2) is equal to.5 times the input current (Vin TLM (V) =.5 *Input Current (A)+/-.V) Short Circuit and Overload Protection: Output current is limited under any load fault condition to approximately 25% of rated. An overload condition causes the converter output voltage to drop below nominal. The converter will resume normal operation when the load current is reduced below the current limit point. This protects the converter from both overload and short circuit conditions. The current limit point exhibits a slightly negative temperature coefficient to reduce the possibility of thermal runaway. Input Under voltage Lockout (UVLO) and Under voltage Release (UVR): The converter is designed to be protected against an under voltage condition. The converter will be in a non-functional (UVLO) mode when the input voltage is approximately 5.5V or less. The converter will turn on when the input voltage rises to 5.5V to 7.9V (defined as UVR threshold) and will provide a regulated output as the input voltage reaches 8V. Should the input voltage drops below 6.5V to 4.5V (defined as UVLO threshold), the converter will turn off and remains off so long as the input voltage remains under the UVLO threshold. The converter will resume a normal operation when the input line rises above the UVR threshold. However, the converter can be configured to remain in a latch-up mode if desired. Output Overvoltage Protection: The converter also features an output over-voltage protection. One OVP circuitry for each output for the dual output models. In an event the voltage output exceeds a preset voltage threshold of approximately 2 +/- 5% of nominal voltage output, the converter will turn off. The input power to the converter or the signal at the Inhibit pin must be recycled (connecting and removing the Inhibit pin to/from Inhibit Return pin) to turn on the converter. This event is possible only if the converter shuts off due to a false triggering. The OVP threshold voltage can also be reset to within 5% to 25% of nominal output voltage with two external resistors. Refer to the Application Notes section of the data sheet on page 9. Inhibit (On/Off Command): An external inhibit port is provided to control converter operation. The converter s operation is inhibited when this pin is pulled low. It is intended to be driven by an open collector logic device. The pin may be left open for normal operation and has a nominal open circuit voltage of 4V with respect to the inhibit return (Pin 4). Output Voltage Adjustment: The output voltage of all models can be adjusted greater or less than the nominal output voltage using a single external resistor. Refer to the Application Notes section of the data sheet on page 9. Design Methodology The LSO Series was developed using a proven conservative design methodology derived from other space level designs that includes selection of established reliability components and fully de-rating to the requirements of MIL-STD-547, MIL-PRF-975 and NASA EEE-INST-2 except for the CDR type ceramic capacitors, a capacitor with 5V rating is used for in-circuit voltage stress of less than V. A magnetic feedback circuit is utilized instead of opto couplers to minimize temperature, aging and radiation sensitivity. PSPICE was used extensively to predict and optimize circuit performance for both beginning and end-of-life. Thorough design analyses include stress, thermal, and reliability (MTBF). To take advantage of the latch-up feature, the U/V Latch Pin (Pin 5) should be shorted (with less than Ohms) to the Inhibit Return Pin (Pin 4). Note that in this mode the converter will latch off if an under voltage condition lasts more than milli-sec. The converter is reset by a shorted Enable Input pin command followed by an open Enable Input pin command. 2 26-9-22

Application Notes: Fig. 4 - Typical Connections Diagram Inhibit Function: The converter is disabled when the INHIBIT pin is shorted to the INHIBIT RETURN with an impedance less than or equal to K ohm, and that the converter be enabled when the impedance between the INHIBIT pin and INHIBIT RETURN is greater than or equal to 5 kohms. Fig. 5 - Inhibit Function Remote Sense: A remote sense feature maintains the desired output voltage regulation at the load. It corrects the voltage drop along the conductors between converter s output and the load. To use this function connect ±sense pins directly to the load as shown in Fig. 6. To use a converter without remote sense function, connect the ±sense pins to output pins respectively. This function is available just on single output models. Fig. 6 - Remote Sense - Single Models 9 26-9-22
Output Voltage Adjustment: Output of LSO singles and duals can be adjusted to be greater or less the nominal output voltage with an external resistor. However, the ranges of the output voltages are limited depending on the model as specified in Table and Table 2. An approximate value of the resistor can be determined using the following formula. For Single Output Model: A - (B * V out ) Radj = (C * V out ) - D For Dual Output Model: A - (B * 2 * V out ) Radj = (C * 2 * V out ) - D Where: Radj is the external resistor in ohms, as shown in Fig 7. Power rating of the resistor shall be.25 W. Metal film resistor with temperature coefficient of ± 5 ppm and tolerance of % is recommended. However, the final selection is dependent on specific design requirements. Vout is the output voltage in volts. A, B, C and D are unique constants depending on every model as shown in Table for single output models and Table 2 for dual output models. Placement of Radj: An external resistor must be added in order to trim the output voltage of a LSO converter. The placement of a Radj resistor must be connected as shown in Fig. 7. Singles: Radj is placed across Out Adj and ± Sense pins. For output voltage greater than nominal voltage, Radj is placed from Out Adj to Sense. To have output voltage less than nominal voltage, place Radj across Out Adj and +Sense. Table 2. LSO285S.

OVP External Adjustment: Over-voltage Protection threshold of LSO singles and duals can be adjusted to be greater or less the nominal OVP with a couple of external resistors. Lower resistors, R and R2 are k resistors, while Radj set the new OVP threshold as stated in Table 6 for single output models and Table 7 for dual output models. Ranges of LSO series converter can be adjusted from 5% to 25% of the nominal output voltage. See Fig.8 to place external resistors. An approximate value of the resistor can be determined using the following formula. Where: (A V ) R * ovp - B adj = C - (D * V ovp) Radj is the upper external resistor in kilo-ohms, as shown in Fig 8. Power rating of the resistor shall be.25 W. Metal film resistor with temperature coefficient of ± 5 ppm and tolerance of % is recommended. However, the final selection is dependent on specific design requirements. Table 7. LSO Duals.

CK is a DLA Land and Maritime (formerly DSCC) part marking used to designate a Class K compliant hybrid. The CK marking does not indicate the hybrid is radiation certified. No suffix is a radiation rated device but not available as a DLA qualified SMD per MIL-PRF-38534. Any Engineering Model (EM) build with the EM Suffix shall only be form, fit and functional equivalent to its Flight Model (FM) counterpart, and it may not meet the radiation performance. The EM Model shall not be expected comply with MIL-PRF-38534 flight quality/workmanship standards, and configuration control. An EM build may use electrical equivalent commercial grade components.
