PIN I/O DESCRIPTION
NAME NO
VIN A2 PWR VIN power supply pin. Connect the input capacitor close to this pin for best noise and voltage spike suppression. A ceramic capacitor of 4.7 µF is required.
SW A1 OUT The switch pin is connected to the internal MOSFET switches. Connect the inductor to this terminal.
GND B2 PWR GND supply pin. Connect this pin close to the GND terminal of the input and output capacitor.
VOS C2 IN Feedback pin for the internal feedback divider network and regulation loop. An internal load switch is connected between VOUT pin and LOAD pin. Connect this pin directly to the output capacitor with a short trace. Discharges VOUT when the converter is disabled.
VSEL C1 IN Output voltage selection pin. See for VOUT selection. This pin must be terminated. The pin can be dynamically changed during operation.
EN B1 IN High level enables the devices, low level turns the device into shutdown mode. The pin must be terminated.
CTRL D1 IN This pin controls the load switch between VOS and LOAD. With CTRL = low, the LOAD switch is disabled. This pin must be terminated.
LOAD D2 OUT Output terminal of the internal load switch. With CTRL = high, the internal load switch connects VOS to the LOAD pin. This pin is pulled to GND with the CTRL = low. If not used, leave the pin open.
