EP53F8QI

1500 mA Synchronous Buck PWM

DC-DC Converter with Integrated Inductor

RoHS Compliant; Halogen Free

Description

Application

• Wireless wide area networking data cards.

The EP53F8QI provides high efficiency in a very

small footprint. Featuring integrated inductor, the

device delivers up to 1500mA of continuous

output current. Total solution footprint can be as

little as 40mm².

• Replacement of inefficient LDOs

• Noise Sensitive Applications such as RF,

Audio and Video, and high speed IO

Output voltage is programmed via an external

resistor divider providing a wide range of

flexibility while maintaining a very small footprint.

• Computing, Computer Peripherals, Storage,

Networking, and Instrumentation

• USB, DSL, STB, DVR, DTV, and iPC

Integration of the inductor reduces conducted

and

radiated

noise

providing

excellent

compatibility with sensitive RF and high speed

data applications.
