MP2452
MP2452 is Step-Down Converter manufactured by Monolithic Power Systems.
DESCRIPTION
The MP2452 is a high frequency (1MHz) stepdown switching regulator with integrated internal high-side high voltage power MOSFET. It provides up to 1A highly efficient output current 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 inductor current runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation.
The MP2452 is available in the 2mm x 3mm QFN8 package.
