Product Overview
The Ultra-Low-Profile EP53X2Q product family is
targeted to applications where board area and
profile are critical. EP53X2Q 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
EP53x2Q family is engineered to simplify design
and to minimize layout constraints. High
switching frequency and internal type III
compensation provides superior transient
response. With a 1.1 mm profile, the EP53x2 is
perfect for space and height limited applications.
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.

Absolute Maximum Ratings
CAUTION: Absolute Maximum ratings are stress ratings only. Functional operation beyond recommended operating
conditions is not implied. Stress beyond absolute maximum ratings may cause permanent damage to the device.
Exposure to absolute maximum rated conditions for extended periods may affect device reliability.
