Microchip Technology MIC2207YML-TR

Description
The MIC2207 is a high-efficiency PWM buck regulator that provides up to 3A of output current. It 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 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 12-pin 3mm x 3mm MLF package with a junction operating range from -40°C to 125°C.
