Positive Supply-Voltage Input. V
Enable Active-Low Input. Drive EN low to enable the switch. Drive EN high to disable the switch.
Open-Drain Adapter-Voltage Indicator Output. ACOK is driven low after the V
between UVLO and OVLO for 30ms (typ). Connect a pullup resistor from ACOK to the logic I/O voltage
of the host system.
Output Voltage. Output of internal switch.
Exposed Pad. Connect exposed pad to ground. Do not use EP as a sole ground connection.
