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.

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
Softstart Input. External capacitor and internal current source sets the softstart time.
Switching frequency select input. Open = F
Factory test pin, connect to ground.
Connect to system ground plane for reduced thermal resistance.
