Pin Name
Sense 1 (Input): Error amplifier input. Connect to feedback resistor network to
set output 1 voltage.
Enable 1 (Input): Logic low will shut down output 1. Logic high powers up
output 1. Do not leave unconnected.
Analog Ground. Must be connected externally to PGND.
Switch Node 1 (Output): Internal power MOSFET output.
Power Ground.
Supply Voltage (Power Input): Requires close bypass capacitor to PGND.
Switch Node 2 (Output): Internal power MOSFET output.
Supply Voltage (Power Input): Analog control circuitry. Connect to VIN.
Enable 2 (Input): Logic low will shut down output 2. Logic high powers up
output 2. Do not leave unconnected.
Sense 2 (Input): Error amplifier input. Connect to feedback resistor network to
set output 2 voltage.
