The LTM®4650A is a dual 25A or single 50A output switching
mode step-down DC/DC μModule® (micromodule) 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 and16mm × 16mm × 5.01mm
BGA packages.
