Datasheet Summary
The Future of Analog IC Technology
DESCRIPTION
The MP2451 is a high frequency (2MHz) stepdown switching regulator with integrated internal high-side high voltage power MOSFET. It provides single 0.6A (or less) highly efficient output with current mode control for fast loop response.
The wide 3.3V to 36V input range acmodates a variety of step-down applications in automotive input environment. A 3μA shutdown mode quiescent current allows use in battery-powered applications.
High power conversion efficiency over a wide load range is achieved by scaling down the switching frequency at light load condition to reduce the switching and gate driving losses.
Frequency fold-back helps prevent...
