Micrel MIC2207 3mmx3mm 2MHz 3A PWM Buck Regulator Datasheet
The Micrel MIC2207 is a high efficiency PWM step-down (buck) regulator designed for applications requiring up to 3A of output current. It operates from a supply voltage range of 2.7V to 5.5V and features proprietary internal compensation allowing a closed loop bandwidth over 200KHz. The device utilizes a low on-resistance internal p-channel MOSFET, enabling efficiencies exceeding 94% while reducing the need for external current sense resistors.
The MIC2207 is available in an exposed pad 3mm x 3mm MLF-12L package with a junction operating temperature range from -40°C to +125°C. Key features include ultra-fast transient response, stable operation with a 1uH inductor and 4.7uF output capacitor, micropower shutdown mode, thermal shutdown protection, and current limit protection.
