3 / 19 page EP53A7LQI/EP53A7HQI PIN NAME FUNCTION 9, 10, 11 VS2, VS1, VS0 Output voltage select. VS2 = pin 9, VS1 = pin 10, VS0 = pin 11. EP53A7LQI: Selects one of seven preset output voltages or an external resistor divider. EP53A7HQI: Selects one of eight preset output voltages. (Refer to section on output voltage select for more details.) 12 ENABLE Output Enable. Enable = logic high; Disable = logic low 13 AVIN Input power supply for the controller circuitry. Connect to PVIN through a 100 Ohm resistor. 14 PVIN 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 cause permanent damage to the device. Exposure to absolute maximum rated conditions for extended periods may affect device reliability.
