The MP4459 is a high frequency step-down switching regulator with an integrated internal high-side high voltage power MOSFET.

Product Detail

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? 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.?In some applications, such as AM radio and ADSL applications, in which the device is sensitive to frequency band, the MP4459 can avoid the related EMI problem by setting the frequency at 4MHz. The MP4459 is available in thin 10-pin 3x3mm TQFN package.
