MIC4744YTSE Description

Short technical summary and product information.

The Micrel MIC4744YTSE is a high-efficiency, dual PWM buck (step-down) regulator designed to provide 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 from 2.9V to 5.5V, and the output voltage can be adjusted down to 0.6V.

 

With efficiencies greater than 90%, the MIC4744YTSE utilizes integrated P-Channel MOSFET switches with low on-resistance. It offers features such as 100% maximum duty cycle for low-dropout conditions, micro-power shutdown, and thermal shutdown and current limit protection. The regulator is available in a 16-pin TSSOP-EP (Exposed Pad) package, suitable for surface mounting.

 

Applications for this regulator include broadband devices like xDSL modems, automotive satellite radios, HD STBs, DVD/TV recorders, computer peripherals such as printers and graphic cards, and FPGA/ASIC power supplies. Its compact size and high performance make it suitable for general point-of-load applications where space and efficiency are critical.
