PIN DESCRIPTIONS
Pin Name Function
1 COMP 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.
2 FB Output voltage feedback input.
3 SHDN Shutdown control input, Open = enable, Ground = disable.
4 AGND Analog ground, connect directly to PGND.
5 PGND Power ground.
6 PGND Power ground.
7 PGND Power ground.
8 PGND Power ground.
9 SW Power switch input. Switch connected between SW pins and PGND pins
10 SW Power switch input. Switch connected between SW pins and PGND pins
11 SW Power switch input. Switch connected between SW pins and PGND pins
12 BYP Bypass-Decouple Capacitor Connection, 0.1µF ceramic capacitor recommended.
13 V
IN
Analog power input. A small RC filter is recommended, to suppress line glitches. Typical values of 10Ω
and ≥ 0.1µF are recommended.
14 SS Softstart Input. External capacitor and internal current source sets the softstart time.
15 FS Switching frequency select input. Open = F
high
. Ground = F
low
16 TEST Factory test pin, connect to ground.
- Exposed Pad Connect to system ground plane for reduced thermal resistance.
