The Micrel MIC4721 is a high-efficiency PWM buck (step-down) regulator capable of delivering up to 1.5A of output current. Operating at a 2MHz switching frequency, it features proprietary internal compensation for a closed-loop bandwidth exceeding 200KHz. Its low on-resistance internal p-channel MOSFET contributes to efficiencies up to 94%, reducing the need for external components and current sense resistors.
The MIC4721 operates from a 2.7V to 5.5V input supply, with an adjustable output voltage down to 1V. It supports a maximum duty cycle of 100% for low-dropout conditions. The device is housed in a 10-pin MSOP package, suitable for surface mounting.
Key features include micropower shutdown, a Power Good pin, and thermal shutdown and current limit protection. This regulator is well-suited for applications such as FPGA/DSP/ASIC power, general point-of-load, broadband communications, and computing peripherals.
