The Micrel MIC4744 is a high-efficiency, dual PWM buck (step-down) regulator providing dual 2A current outputs. It operates at a 4MHz switching frequency, enabling the use of ultra-small external components like a 0.47µH inductor and a 10µF output capacitor. The device accepts an input voltage range of 2.9V to 5.5V and allows the output voltage to be adjusted down to 0.6V. Its internal P-Channel MOSFETs offer efficiencies greater than 90% and include thermal shutdown and current limit protection.
The MIC4744 is available in a 16-pin 3mm x 3mm MLF® package and a 16-pin ETSSOP package. This specific part, the MIC4744YTSE-TR, comes in the 16-TSSOP-EP package, which is suitable for surface mounting. The junction operating temperature ranges from -40°C to +125°C.
Applications for this regulator include broadband devices like xDSL modems, automotive satellite radios, HD STB, DVD/TV recorders, computer peripherals such as printers and graphic cards, FPGA/ASIC power, and general point-of-load applications.
