General Description
The MIC2203 is an ultra-high efficiency, high frequency synchronous buck (step-down) switching regulator.
Efficiencies above 90% are easily obtainable for a wide variety of applications.
Key Features
- internal power MOSFETs that can supply up to 300mA output current. It can operate with a maximum duty cycle of 100% for low-dropout conditions and regulate output voltages down to 0.5V. The MIC2203 is a constant frequency pulse width modulation (PWM) buck converter that maintains high efficiency even at light load currents. By maintaining a constant PWM frequency, RF interference is kept down to a minimum. The MIC2203 has a SYNC_IN pin and SYNC_OUT function, which can be used to synchronize the.
