1 XC691 Series ETR mA Negative Voltage Regulator with ON/OFF Control GENERAL DESCRIPTION The XC691 Series is a negative voltage CMOS regulator which includes a reference voltage source, error amplifier, driver transistor, current limiter and phase compensator. The CE function enables the circuit to be in stand-by mode by inputting low level signal. In the stand-by mode, the electric charge at the output capacitor (C L ) will be discharged via the internal auto-discharge switch and as a result the -V OUT pin quickly returns to the V SS level. The over current protection circuit will operate when the output current reaches limit current. The thermal shutdown circuit will operate when the junction temperature reaches limit temperature.

10 XC691 Series OPERATIONAL EXPLANATION The voltage divided by resisters R1 and R2 is compared with the internal reference voltage based on ground by the error amplifier. The driver transistor tied to the V IN pin is then driven by the subsequent output signal. The output voltage at the V OUT pin is controlled and stabilized by a system of negative feedback. <Soft Start Function> XC691 Series includes soft-start circuit. During power start-up, the inrush current from -V IN pin to V OUT pin to charge C L capacitor can be reduced and it makes the V IN stable. Soft-start time (t SS ) is optimized internally. Figure1:Soft Start Time and Inrush Current <Current Limit, Short-Circuit Protection> The XC691 series fold-back circuit operates as an output current limiter and a short protection circuit for the output pin. When the output current reaches the current limit level, output voltage drops with the decrease of the output current. There are no parasitic diode between the V OUT pin and GND pin. The minimized short-circuit current is maintained even if the V OUT pin voltage is pulled up toward positive. <Thermal Shutdown> The XC691 Series has an internal thermal Shutdown(TSD) circuit for protection against overheating. When the junction temperature reaches the detection temperature, the driver transistor is forcibly turned off. When the junction temperature falls to the release temperature with the driver transistor still in the off state, the driver transistor turns on (automatic recovery) and restarts regulator operation. <CE Pin> The XC691 Series is able to shut down the regulator circuit using the CE pin signal. CE pin can be controlled with positive voltage due to P-channel transistor source input (Gate is grounded). A current flow of a few micro amperes. The regulator is turned on when CE input voltage is positive, the regulator is turned off when CE input is GND. When CE pin is open, IC is turned OFF, due to the built-in Pull-down resistor. When the IC is turned OFF with low input voltage to the CE pin,-v OUT pin voltage goes into GND level by R1,R2 and CL discharge resistance(r DCHG ). 1/28

11 XC691 Series OPERATIONAL EXPLANATION(Continued) <C L High Speed Discharge> The XC691D type is capable of high-speed discharge of the charge that collects on the output capacitor (C L below). This is accomplished by the P-channel MOSFET and C L discharge resistance connected between the -V OUT and GND pins in the block diagram, and takes place when the L-level signal (IC internal circuit shutdown signal) of the CE pin is input so that it could avoids malfunction. The C L discharge time is determined by this C L discharge resistance and C L. Letting the time constant of the C L discharge resistance R DCHG and C L be τ (τ = C R), the output voltage after discharge by the P-channel MOSFET can be obtained from the CR discharge equation below. Please be noted that R DCHG various with supply voltage and V DS (drain-source voltage) since it consists of P-channel MOSFET. t = τln(v OUT(E) / V) V:Output voltage during discharge V OUT(E) :Output voltage t:discharge time τ:c L auto-discharge resistance R DCHG C L Output capacitor value C L <Low ESR Capacitor> With the XC691 series, a stable output voltage is achievable even if used with low ESR capacitors, as a phase compensation circuit is built-in. The output capacitor (C L ) should be connected as close to -V OUT pin and GND pin to obtain stable phase compensation. Values required for the phase compensation are as the table below. For a stable power input, please connect an input capacitor (C IN ) near power supply. In order to ensure the stable phase compensation while avoiding run-out of values, please use the capacitor (C IN, C L ) which does not depend on bias or temperature too much. The table below shows recommended values of C IN, C L for all environment conditions. CHART 1:Recommended Values of C IN, C L (MIN.)

12 XC691 Series NOTE ON USE 1) For temporary, transitional voltage drop or voltage rising phenomenon. The IC is liable to malfunction should the ratings be exceeded. 2) Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current. Please enforce wiring V IN and GND. 3) Please wire the C IN and C L as close to the IC as possible. 4) Capacitances of these capacitors (C IN, C L ) are decreased by the influences of bias voltage and ambient temperature. Care shall be taken for capacitor selection to ensure stability of phase compensation from the point of ESR influence. 5) Torex places an importance on improving our products and its reliability. However, by any possibility, we would request user fail-safe design and post-aging treatment on system or equipment. 12/28
