LTM4614 - Dual 4A per Channel Low VIN DC/DC μModule (Power Module) Regulator

The LTM4614 is a complete 4A dual output switching mode DC/DC power supply. Included in the package are the switching controllers, power FETs, inductors and all support components. The dual 4A DC/DC converters operate over an input voltage range of 2.375V to 5.5V. The LTM4614 supports output voltages ranging from 0.8V to 5V. The regulator output voltages are set by a single resistor for each output. Only bulk input and output capacitors are needed to complete the design. The low profile package (2.82mm) enables utilization of unused space on the bottom of PC boards for high density point of load regulation. Additional features include overvoltage protection, foldback overcurrent protection, thermal shutdown and programmable soft-start. The power module is offered in a space saving and thermally enhanced 15mm × 15mm × 2.82mm LGA package. The LTM4614 is Pb-free and RoHS compliant.
