MIC2207

3mmx3mm 2MHz 3A PWM Buck

Regulator

General Description

Features

The Micrel MIC2207 is a high efficiency PWM buck

(step-down) regulators that provides up to 3A of

output current. The MIC2207 operates at 2MHz and

has proprietary internal compensation that allows a

closed loop bandwidth of over 200KHz.

•

2.7 to 5.5V supply voltage

2MHz PWM mode

Output current to 3A

>94% efficiency

100% maximum duty cycle

Adjustable output voltage option down to 1V

Ultra-fast transient response

The low on-resistance internal p-channel MOSFET

of the MIC2207 allows efficiencies over 94%,

reduces external components count and eliminates

the need for an expensive current sense resistor.

Ultra-small external components

Stable with a 1µH inductor and a 4.7µF

output capacitor

The MIC2207 operates from 2.7V to 5.5V input and

the output can be adjusted down to 1V. The devices

can operate with a maximum duty cycle of 100% for

use in low-dropout conditions.

•

Fully integrated 3A MOSFET switch

Micropower shutdown

The MIC2207 is available in the exposed pad 3mm x

3mm MLF-12L package with a junction operating

range from –40°C to +125°C.

Thermal shutdown and current limit

protection

•

Pb-free 3mm x 3mm MLF-12L package

–40°C to +125°C junction temperature range

Applications

•

5V or 3.3V Point of Load Conversion

Telecom/Networking Equipment

Set Top Boxes

Storage Equipment

Video Cards
