800mA Synchronous Buck Regulator

With Integrated Inductor

3mm x 3mm x 1.1mm Package

July 2008

RoHS Compliant

Halogen Free

Product Overview

Product Highlights

The EP5388QI is a synchronous buck

converter with integrated Inductor, PWM

controller, MOSFETS, and Compensation

providing the smallest possible solution size.

The EP5388QI requires only two small MLCC

capacitors to make a complete solution.

Integration of the inductor greatly simplifies

design, contains noise, reduces part count, and

reduces solution footprint. Low output ripple

ensures compatibility with RF systems.

Featuring Integrated Inductor Technology

• 3mm x 3mm x 1.1mm QFN package

• Only two low cost MLCC caps required

• 4 MHz switching frequency

• High efficiency, up to 94%

• Up to 800mA continuous output current

• Wide 2.4V to 5.5V input range

The EP5388QI operates at a switching

frequency

MHz,

enabling

this

unprecedented level of integration and small

external components. Type III voltage mode

control is used to provide high noise immunity

and wide control loop bandwidth.

The small footprint makes this part ideal for

space constrained portable applications.

Shutdown current of <1uA extends battery life

Output voltage level is programmed via a 3-pin

VID selector providing seven pre-programmed

output voltages along with an option for

external resistor divider.

• V_OUTrange 0.6V to V_IN– 0.5V

• 3-Pin VID output voltage programming

• 100% duty cycle capable

• Less than 1 µA standby current

• Low V_OUTripple for RF compatibility

• Short circuit and over current protection

• UVLO and thermal protection

Applications

• Noise Sensitive RF Applications

• Area Constrained Applications

• Wireless Data Applications

• RoHS compliant; MSL 3 260°C reflow
