MP2451DJ-LF-Z

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 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.
