1.5A, 4MHz, 36V Step-down Converter

The MP4459 is a high frequency Step-down Switching Regulator with an integrated internal high-side high voltage Power MOSFET It provides 1.5A output with current mode control for fast loop response and easy compensation. The wide 4.5V to 36V input range accommodates a variety of Step-down applications, including those in automotive systems. A 100,A operational quiescent current is suitable for use in battery-powered applications. The frequency foldback helps prevent inductor current runaway during startup and thermal shutdown provides reliable, fault tolerant operation. By switching at 4MHz, the MP4459 prevents EMI (Electromagnetic Interference) noise problems, such as those found in AM Radio and ADSL applications. The MP4459 is available in thin 10-pin 3mm x 3mm TQFN package.
