MIC2202YMM-TR

The Micrel MIC2202 is a high-efficiency 2MHz PWM synchronous buck regulator designed for compact and cost-effective power solutions. Its fast 2MHz operation and proprietary compensation scheme allow for the use of small external components, including a 1µF ceramic output capacitor and a 2.2µH inductor.

This regulator operates from a 2.3V to 5.5V input voltage range and features internal power MOSFETs capable of delivering over 600mA of output current with output voltages adjustable down to 0.5V. The constant 2MHz PWM control scheme minimizes noise, making it suitable for sensitive RF, audio, and communications applications. The MIC2202 also offers an ultra-fast transient response with a high bandwidth loop (up to 500kHz GBW).

Available in a 10-pin MSOP package, the MIC2202 is designed for surface mounting. It operates within a junction temperature range of -40°C to +125°C. The device is well-suited for applications such as cellular phones, PDAs, and WLAN power supplies, where space and efficiency are critical.

Key features include internal compensation, fully integrated MOSFET switches, and the ability to be synchronized to an external clock. It requires only four external components for basic operation and offers 1% line and load regulation.
