PIN FUNCTIONS
Pin # Name Description
1
EN1
Channel 1 Enable Control Input. Drive EN1 above 1.5V to turn on the Channel 1. Drive EN1
below 0.3V to turn it off (shutdown current < 0.1μA).
Channel 1 Feedback Input. Connect FB1 to the center point of the external resistor divider. The
feedback voltage is 0.6V.
Channel 2 Supply Input. Bypass to GND with a 2.2μF or greater ceramic capacitor.
GND2 Ground 2.
Channel 2 Power Switch Output. Inductor connection to drains of the internal PFET and NFET
switches.
