Description

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.

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.

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.

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.
