Pin Descriptions
Pin Pin Name Pin Function
1
EN1
Active high enable pin for device 1. Connect to VIN1 if not being used.
2
GND
Ground pin. Can be used for heatsinking if needed. Electrically connected to pin 7.
3
SET 1 Connecting this pin to ground results in the internally preset value for VOUT1. Connecting to an external
resistor divider changes VOUT1 to:
VOUT 1
=
1.250
