Micrel MIC2207 Evaluation Board User Guide
The Micrel MIC2207 is a high efficiency PWM buck (step-down) 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 200 KHz. The low on-resistance internal p-channel MOSFET of the MIC2207 allows efficiencies over 94% and reduces external component count.
The evaluation board requires an input power source able to deliver greater than 2.7V at over 3A. The output voltage is adjustable from a default of 1.8V down to 1V by changing the feedback resistors. Users must ensure the supply voltage remains between 2.7V and 5.5V to avoid damage.
