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.
