PIN I/O DESCRIPTION
NO. NAME
1 EN I Device enable. A high level applied to this pin enables the device and a low level disables it. It must not be left open.
2 SEL I Output voltage select. Selects VO(2) when a high level is applied to this pin. Selects VO(1) when a low level is applied to this pin. It must not be left open.
3 CFG1 I Configuration pin 1. Connect a resistor between this pin and ground to set VO(2) and input current limit, must not be left open.
4 CFG2 I Configuration pin 2. Connect a resistor between this pin and ground to set VO(2) and input current limit. Must not be left open.
5 CFG3 I Configuration pin 3. Connect a resistor between this pin and ground to set VO(1). Must not be left open.
6 VOUT — Output voltage
7 LX2 — Switching node of the boost stage
8 GND — Ground
9 LX1 — Switching node of the buck stage
10 VIN — Supply voltage
— Thermal Pad — Connect this pin to ground for correct operation.
