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. Discharges VOUT when the converter is disabled. Connect this pin directly to the output capacitor with a short trace.
VSEL3 D2 IN Output voltage selection pins. See Table 6-2 for VOUT selection. These pin must be terminated. The pins can be dynamically changed during operation.
VSEL2 D1 IN
VSEL1 C1 IN
EN B1 IN High level enables the devices, low level turns the device off. The pin must be terminated.
