DESCRIPTION
The LTM®4652 is a source/sink dual ±25A or single ±50A
output switching mode step-down DC/DC μModule®
(micromodule) regulator with ±1.5% total DC output
error. Included in the package are the switching controllers,
power MOSFETs, inductors and all supporting
components. Operating from an input voltage range of
4.5V to 18V, the LTM4652 supports two outputs with an
output voltage range of 0.6V to 7.5V, each set by a single
external resistor. Its high efficiency design delivers up to
±25A continuous current for each output. Only a few input
and output capacitors are needed. Adjustable control loop
compensation allows for fast transient response to minimize
output capacitance when powering FPGAs, ASICs,
and processors.
Fault protection features include input and output overvoltage
and bidirectional overcurrent protection. The
LTM4652 is offered in a 16mm × 16mm × 4.92mm BGA package.
