Compensation network connection. Connected to the output of the voltage error amplifier.
The RC compenstion network should be connected from this pin to AGND. An additional
100pF high frequency capacitor to AGND is recommended.
Output voltage feedback input.
Shutdown control input, Open = enable, Ground = disable.
Analog ground, connect directly to PGND.

Power switch input. Switch connected between SW pins and PGND pins
Power switch input. Switch connected between SW pins and PGND pins
Power switch input. Switch connected between SW pins and PGND pins
Bypass-Decouple Capacitor Connection, 0.1µF ceramic capacitor recommended.
Analog power input. A small RC filter is recommended, to suppress line glitches. Typical
values of 10Ω and ≥ 0.1µF are recommended.
Softstart Input. External capacitor and internal current source sets the softstart time.
Switching frequency select input. Open = F
Factory test pin, connect to ground.
