Product Overview
The Ultra-Low-Profile EP53X2QI product family
is targeted to applications where board area and
profile are critical. EP53X2QI is a complete
power conversion solution requiring only two low
cost ceramic MLCC caps. Inductor, MOSFETS,
PWM, and compensation are integrated into a
tiny 5mm x 4mm x 1.1mm QFN package. The
EP53x2QI family is engineered to simplify design

A 3-pin VID output voltage select scheme
provides seven pre-programmed output voltages
along with an option for external resistor divider.
Output voltage can be programmed on-the-fly to
provide fast, dynamic voltage scaling.
