Single Output Full Function

Soft start pin. External capacitor provides soft start. Pulling soft start pin low

Non inverting input of the error amplifier (reference Voltage pin). Connect a

Power Good pin. Open collector, requires external pulll-up. If function not

External Clock synchronization pin. Set free running frequency to 80% of

Switching frequency setting pin. For R

will disable the output. Cannot be cycled to unlatch OVP trip

the SYNC frequency. When not in use, leave pin floating

PWM controller power supply pin. Internally generated.

Requires a 2.2µf external bypass capacitor
