Device Overview

Summary

The Micrel MIC2208 is a high efficiency PWM buck (step-down) regulator that provides up to 3A of output current. The MIC2208 operates at 1MHz and has external compensation that allows a closed loop bandwidth of over 100kHz. 

The low on-resistance internal p-channel MOSFET of the MIC2208 allows efficiencies over 94%, reduces external component count and eliminates the need for an expensive current sense resistor.

The MIC2208 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.

The MIC2208 is available in the exposed pad 12-pin 3mm x 3mm MLF® package with a junction operating range from -40°C to +125°C.
