FUNCTION
Output voltage select. VS2 = pin 9, VS1 = pin 10, VS0 = pin 11.
EP53A8LQA: Selects one of seven preset output voltages or an external resistor divider.
EP53A8HQA: Selects one of eight preset output voltages.
(Refer to section on output voltage select for more details.)
Output Enable. Enable = logic high; Disable = logic low
Input power supply for the controller circuitry. Connect to PVIN through a 100 Ohm resistor.
Input Voltage for the MOSFET switches.
Absolute Maximum Ratings
CAUTION: Absolute Maximum ratings are stress ratings only. Functional operation beyond the recommended operating
conditions is not implied. Stress beyond the absolute maximum ratings may impair device life. Exposure to absolute
maximum rated conditions for extended periods may affect device reliability.
