The LTM4710-1 is a quad DC/DC step-down μModule (micromodule) regulator with 8A per output. The package includes the switching controllers, the power MOSFETs, inductors and all supported components. Operating over an input voltage range of 2.5V to 5.5V. Channel 1’s output voltage can be set by only one external resistor, where the outputs for channel 2, channel 3, and channel 4 can be set by two external resistors. All output voltages are programmable up to 3.6V.

The LTM4710-1 employs Silent Switcher 2 architecture with internal hot loop bypass capacitors to achieve both low Electromagnetic Interference (EMI) and high efficiency. The LTM4710-1 is packaged in a compact (6mm × 12mm × 3.54mm) LGA with presolder package and is RoHS compliant.
