MIC2207
3mm x 3mm 2MHz 3A PWM Buck
Regulator General Description Features The Micrel MIC2207 is a high-efficiency PWM buck (stepdown) 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 lowdropout conditions.
The MIC2207 is available in the exposed pad 12-pin
3mm x 3mm MLFВ® package with a junction operating
range from –40°C to +125°C.
