PINTYPE(1)DESCRIPTION
NAMENO.
GND1PWRGND supply pin. Connect this pin close to the GND terminal of the input and output capacitor.
VIN2PWRVIN power supply pin. Connect the input capacitor close to this pin for best noise and voltage spike suppression. A ceramic capacitor is required.
VOUT 6 PWR Output voltage of the module. Connect this pin to the output capacitor.
VSET3IConnecting a resistor to GND selects a pre-defined output voltage.
VOS7IOutput 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.
SW5OThis pin is the switch pin of the converter. This pin connects to the internal power MOSFET and the inductor. Avoid connecting this pin to larger traces as this action can increase EMI. This pin can stay unconnected or be soldered to a small pad for thermal improvement.
EN4IA high level enables the devices and a low level turns the device off. The pin features an internal pulldown resistor, which is disabled after the device has started up.
