Product Highlight

  • Topology: Buck
  • Input Voltage: 2.7 to 5.5 V
  • Output Current-Max: 3 A
  • Switching Frequency-Max: 2 MHz

The MIC2207YMLTR is a high efficiency PWM buck (step-down) regulators that provides up to 3 A of output current. The MIC2207 operates at 2 MHz 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%, reduces external components count and eliminates the need for an expensive current sense resistor. The MIC2207 operates from 2.7 V to 5.5 V input and the output can be adjusted down to 1 V. The devices can operate with a maximum duty cycle of 100% for use in low-dropout conditions.
