MP2451DT MP2451 MP2451DT-LF-Z SOT23-6 (silk screen IV7) SMD power management chip In Stock

DESCRIPTION

The MP2451 is a high frequency (2MHz) step- down 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.
