Part details & applications

The LTM4652 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.
