The MPS International Ltd 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 100μA 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.

Up to 4MHz programmable switching frequency
Ceramic capacitor stable
Internal soft start
Precision current limit without a current sensing resistor
Up to 95% efficiency
Output adjustable from 0.8V to 36V
