FUNCTION
Error-Amplifier Output. COMP can be used for soft-start.
Error-Amplifier Inverting Input
PWM Comparator and Overcurrent Protection Comparator Input. The current-sense signal is
compared to a signal proportional to the error-amplifier output voltage.
Timing Resistor/Capacitor Connection. A resistor R T from R T /C T to REF and capacitor C T from R T /C T
to GND set the oscillator frequency.
Power-Supply Ground. Place the V CC and REF bypass capacitors close to the IC to minimize ground
loops.
MOSFET Driver Output. OUT connects to the gate of the external n-channel MOSFET.
Power-Supply Input. Bypass V CC to GND with a 0.1μF ceramic capacitor or a parallel combination of
a 0.1μF and a higher value ceramic capacitor.
5V Reference Output. Bypass REF to GND with a 0.1μF ceramic capacitor or a parallel combination
of a 0.1μF and a higher value ceramic capacitor no larger then 4.7μF.
