Product Introduction
The LTM4650A is a dual 25A or single 50A output switching mode step-down DC/DC µModule regulator with ±1% total DC output error. Included in the package are the switching controllers, power FETs, inductors and all supporting components. Operating from an input voltage range of 4.5V to 16V, the LTM4650A supports two outputs with an output voltage range of 0.6V to 5.5V, each set by a single external resistor. Its high efficiency design delivers up to 25A continuous current for each output. Fast internal control loop compensation allows for fast transient response to minimize output capacitance when powering FPGAs, ASICs, and processors.
Fault protection features include overvoltage and overcurrent protection. The LTM4650A is offered in 16mm × 16mm × 4.41mm LGA and 16mm × 16mm × 5.01mm BGA packages.
