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 accommodates 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 inductor current runaway during
start-up. Thermal shutdown provides reliable, fault-tolerant
operation.
The MP2451 is available in the cost-effective SOT23-6 and TSOT23-6
packages.
