The Micrel MIC4742YML-TR is a high-efficiency, dual PWM buck (step-down) regulator designed to provide dual 2A current outputs. It operates at a 2MHz switching frequency, enabling the use of ultra-small external components. The regulator accepts an input voltage range of 2.9V to 5.5V and allows for adjustable output voltages down to 0.6V.
Key features include efficiencies greater than 92%, a 100% maximum duty cycle for low-dropout conditions, and ultra-fast transient response. The device integrates 2A P-Channel MOSFET switches, reducing external component count and eliminating the need for a current sense resistor. It also includes micro-power shutdown, thermal shutdown, and current limit protection.
The MIC4742YML-TR is available in a 16-pin 3mm x 3mm MLF® package, suitable for surface mounting. The junction operating temperature range is from -40°C to +125°C.
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.
