The MPQ4458 is a high frequency step-down switching regulator with an integrated internal high-side high voltage power MOSFET.

Product Detail

The MPQ4458 is a high frequency step-down switching regulator with an integrated internal high-side high voltage power MOSFET. It provides 1 A 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.? By switching at 4MHz, the MPQ4458 prevents EMI (Electromagnetic Interference) noise problems, such as those found in AM radio and ADSL applications.?The MPQ4458 is available in thin 10-pin 3x3mm TQFN package.
