Mnemonic

Description

24, 25

SW1

Switch Node for Channel 1.

26, 27

PVIN1

Power Input for Channel 1. These pins are the power inputs for Channel 1 and provide power for the internal

regulator. Connect to the input power source and connect a bypass capacitor between PVIN1 and ground.

28

EN1

Enable Pin for Channel 1. An external resistor divider can be used to set the turn-on threshold. When not using

the enable pin, connect EN1 to PVIN1.

29

TRK1

Tracking Input for Channel 1. To track a master voltage, connect this pin to a resistor divider from the master

voltage. If the tracking function is not used, connect TRK1 to INTVCC.

30

SS1

Soft Start Control for Channel 1. To program the soft start time, connect a capacitor from SS1 to GND.

31

COMP1

Error Amplifier Output for Channel 1. Connect an RC network from COMP1 to GND. Connect COMP1 and COMP2

together for parallel applications.

32

FB1

N/A1

EP

Exposed Pad. Solder the exposed pad to an external GND plane.
