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.
