Table 1. Pin Functions

PIN I/O DESCRIPTION
NAME NO
VIN C3 IN Input voltage supply pin of the module.
GND C2 - Ground terminal.
CTRL B2 IN CTRL pin controls the LOAD output pin. With CTRL = low, the LOAD output is disabled. This pin must be terminated and not left floating.
VOUT C1 OUT Output voltage pin of the module. An internal load switch is connected between VOUT pin and LOAD pin.
LOAD B1 OUT Load switch output pin controlled by the CTRL pin. With CTRL = high, an internal load switch connects the LOAD pin to the VOUT pin. The LOAD pin allows connect / disconnect other system components to the output of the DC/DC converter. This pin is pulled to GND with the CTRL pin = low. The LOAD pin features soft switching. If not used, leave the pin open.
VSEL3 A1 IN Output voltage selection pins. See Table 2 and Table 3 for VOUT selection. These pins must be terminated and can be changed during operation.
VSEL2 A2 IN
VSEL1 A3 IN
EN B3 IN High level enables the devices and low level turns the device into shutdown mode. This pin must be terminated and not left floating.
