MIC2202

MIC2202 High Efficiency 2MHz Synchronous Buck Converter 1µF Stable PWM Regulator General Description Features The Micrel MIC2202 is a high efficiency 2MHz PWM synchronous buck regulator. The fast 2MHz operation along with a proprietary compensation scheme allows the smallest possible external components. The MIC2202 can operate with a 1µF ceramic output capacitor and a small, low DC-resistance, 2.2µH inductor, reducing system size and cost while allowing a high level of efficiency. The MIC2202 operates from 2.3V to 5.5V input and features internal power MOSFETs that can supply over 600mA of output current with output voltages down to 0.5V. The MIC2202 implements a constant 2MHz pulsewidth-modu-lation (PWM) control scheme which reduces noise in sensitive RF, audio, and communications applications. Additionally, the MIC2202 can be synchronized to an external clock, or multiple MIC2202s can easily be daisy-chained with the SYNCLOCK feature. The MIC2202 has a high bandwidth loop (up ...
