The vertical mounting option of the PTV1 module provides performance in less than % of the space that is required by alternative solutions. The uto- feature provides for sequencing between multiple modules, a function, which is becoming a necessity for powering advanced silicon including DSP s, FPG s and SIC s requiring controlled power-up and power-down. The PTV1 has an input voltage of 10.8 Vdc to 13.2 Vdc and offers a wide 1.2 Vdc to 5.5 Vdc for suffix W and 0.8 Vdc to 1.8 Vdc for suffix L output voltage range with up to 16 output current, which allows for maximum design flexibility and a pathway for future upgrades. ll specifications are typical at nominal input, full load at 25 C unless otherwise stated C in = 5 µf (non-ceramic) and 22 µf (ceramic), C out = 0 µf 2 YER WRRNTY SPECIFICTIONS OUTPUT SPECIFICTIONS ltage adjustability Suffix W Vdc (See Note 4) Vdc Setpoint accuracy (See Note 8) ±2.0% Line regulation Suffix W ±5 mv typ. ±10 mv typ.

Pin Length (0.1 ) Output ltage Code W = Wide, L = Low ltage Mechanical Package lways 0 Output ltage djustment of the PTV1 Series The ultra-wide output voltage trim range offers major advantages to users who select the PTV1. It is no longer necessary to purchase a variety of modules in order to cover different output voltages. The output voltage can be trimmed in a range of 1.2 Vdc to 5.5 Vdc for suffix W and 0.8 Vdc to 1.8 Vdc for suffix L. When the PTV1 converter leaves the factory the output has been adjusted to the default voltage of 1.2 V for the PTV1W and 0.8 V for PTV1L.

The electrolytic capacitor must be rated for the minimum rms of ripple current. 4 n external output capacitor is not required for basic operation. dding 3 µf of distributed capacitance at the load will improve the transient response. 5 1 /µs load step, to 100% I omax, C3 = 3 µf. 6 If utilized ut will track applied voltage by ±0.3 V (up to set point). 7 The pre-bias start-up feature is not compatible with uto-. This is because when the module is under uto- control, it is fully active and will sink current if the output voltage is below that of a back-feeding source. Therefore to ensure a pre-bias hold-off, one of the following two techniques must be followed when input power is first applied to the module. The uto- function must either be disabled, or the module s output held off using the pin. Refer to pplication Note 199 for more details. 8 The set-point voltage tolerance is affected by the tolerance and stability of R set. The stated limit is unconditionally met if R set has a tolerance of 1% with 100/ºC or better temperature stability. 9 To order Pb-free (RoHS compatible) through-hole parts replace the mounting option H with D, e.g. PTV1WD. 10 NOTICE: Some models do not support all options.
