MIC2202YML

The Micrel MIC2202YML is a high-efficiency, 2MHz PWM synchronous buck regulator designed for compact and cost-effective power solutions. It operates from an input voltage range of 2.3V to 5.5V and can deliver up to 600mA of output current with an adjustable output voltage down to 0.5V. The fast 2MHz switching frequency, combined with a proprietary compensation scheme, allows for the use of small external components, such as a 1µF ceramic output capacitor and a 2.2µH inductor, significantly reducing system size.

This regulator features internal power MOSFETs, internal compensation, and a high bandwidth loop (up to 500kHz) for ultra-fast transient response times. It is suitable for applications requiring dynamic response, such as CPU cores and RF circuitry in mobile devices. The MIC2202YML is available in a 10-pin MLF® package and operates over a junction temperature range of -40°C to +125°C.

Key electrical characteristics include 1% line and load regulation, and efficiencies greater than 95%. The device can be synchronized to an external clock or daisy-chained using the SYNCLOCK feature. It also includes logic-controlled micropower shutdown, thermal shutdown, and current limit protection.
