The Future of Analog IC Technology
DESCRIPTION
The MP2454 is a frequency-programmable (350kHz to 2.
3MHz), step-down switching regulator with an integrated internal high-side, high-
voltage power
MOSFET.
It outputs efficiently up to 0.
6A and has current-mode control for fast loop response.
The wide 3.
3V to 36V input range accommodates a variety of step-down applications in automotiveinput environments.
A 3.
5μA shutdown mode quiescent current allows for use in batterypowered applications.
Also, the device has a high duty cycle and low drop-out mode for automotive cold-crank conditions.
The MP2454 achieves high-power conversion efficiency over a wide load range by scaling down the switching freq...
