PIN TYPE DESCRIPTION
NAME NO.
GND A1 PWR GND supply pin. Connect this pin close to the GND terminal of the input and output capacitor.
VIN B1 PWR VIN power supply pin. Connect the input capacitor close to this pin for best noise and voltage spike suppression. A ceramic capacitor is required.
VSET C1 I Connecting a resistor to GND selects a pre-defined output voltage.
VOS A2 I Output voltage sense pin for the internal feedback divider network and regulation loop. This pin also discharges VOUT by an internal MOSFET when the converter is disabled. Connect this pin directly to the output capacitor with a short trace.
SW B2 O The switch pin is connected to the internal MOSFET switches. Connect the inductor to this terminal.
EN C2 I A high level enables the devices and a low level turns the device off. The pin features an internal pulldown resistor, which is disabled once the device has started up.
