Function
Enable pin for Channel 1. Active high. When connected low, it disables the channel and consumes less
than 1μA of current.
Feedback input pin for Channel 1. This pin is connected to the converter output. It is used to see the
output of the converter to regulate to the desired value via an external resistor divider.
Ground.
Enable pin for Channel 2. Active high. When connected low, it disables the channel and consumes less
than 1μA of current.
Feedback input pin for Channel 2. This pin is connected to the converter output. It is used to see the
output of the converter to regulate to the desired value via an external resistor divider.
Power switching node for Channel 2. Output switching node that connects to the output inductor.
Input supply voltage for Channel 2. Must be closely decoupled.
