Synchronous Step-Down Converter
BD90541MUV-C
General Description
The BD90541MUV-C is a synchronous step-down
converter which operates in current mode. It can operate
with maximum frequency of 2.4 MHz, and can downsize
external parts such as inductor. It can supply a maximum
output current of 4A with built-in Pch and Nch output
MOSFET. Output voltage and oscillation frequency can
be adjusted by external resistors and can also be
synchronized with an external clock.
