Table 5-1 Pin Functions
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.
VSEL/MODE C1 IN Connecting a resistor to GND selects a pre-defined output voltage. After the device has started up, the R2D converter is disabled and the pin operates as an input. Applying a high level selects forced PWM mode operation and a low level power save mode operation.
VOS A2 IN 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 OUT The switch pin is connected to the internal MOSFET switches. Connect the inductor to this terminal.
EN C2 IN A 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.
