startup to reduce output voltage overshoot (soft finish network). Diode D4 also isolates
C10 from the supply feedback loop after startup. Resistor R7 discharges C10 when the
supply is off.
Components C3, C9, R5, R6, and R8 all play a role in compensating the power supply
control loop. Capacitor C3 rolls off the gain of U1 at relatively low frequency. Resistor
R5 provides a zero to cancel the phase shift of C5. Resistor R6 sets the gain of the direct
signal path from the supply output through U2 and U3. Components C9 and R8 roll off
the gain of U3.
