Description

+2.7V to + 5.5V Power Supply Voltage. Input to the internal PFET switch.

+2.7V to + 5.5V Analog Supply Input. Bypass this pin to GND with a ≥10µF

capacitor.

Active-High Enable Input. Set this digital input high for normal operation. For

shutdown, set low.

Voltage Control Analog Input. VCON controls VOUT.

Feedback Pin. Connect to the output at the output filter capacitor.

Analog and Control Ground. Connect this pin with low resistance to PGND.

Power Ground. Connect this pin with low resistance to AGND.

Switch Pin. Switch node connection to the internal PFET switch and NFET

synchronous rectifier. Limit specification of the AS1332.
