Pin Descriptions
PIN NAME FUNCTION
1 COMP Error-Amplifier Output. COMP can be used for soft-start.
2 FB Error-Amplifier Inverting Input
3CS
PWM Comparator and Overcurrent Protection Comparator Input. The current-sense signal is
compared to a signal proportional to the error-amplifier output voltage.

to GND set the oscillator frequency.
5 GND
Power-Supply Ground. Place the V

and REF bypass capacitors close to the IC to minimize ground
loops.
6 OUT MOSFET Driver Output. OUT connects to the gate of the external n-channel MOSFET.
7V
CC
Power-Supply Input. Bypass V

to GND with a 0.1µF ceramic capacitor or a parallel combination of
a 0.1µF and a higher value ceramic capacitor.
8 REF
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.
