LTM4623 Step-Down DC/DC μModule Regulator
Analog Devices' 20 VIN, 3 A LTM4623 in a 6.25 mm × 6.25 mm × 1.82 mm ultra-thin LGA package
The LTM4623 from Analog Devices is a complete 3 A step-down switching mode μModule (micromodule) regulator in a tiny, ultra-thin 6.25 mm x 6.25 mm x 1.82 mm LGA package. Included in the package are the switching controller, power FETs, inductor, and support components. Operating over an input-voltage range of 4 V to 20 V or 2.375 V to 20 V with an external bias supply, the LTM4623 supports an output-voltage range of 0.6 V to 5.5 V set by a single external resistor. Its high-efficiency design delivers 3 A continuous output current. Only ceramic input- and output-capacitors are needed.
The LTM4623 supports selectable discontinuous-mode operation and output-voltage tracking for supply-rail sequencing. Its high-switching frequency and current mode control enable a very fast transient response to line and load changes without sacrificing stability.
Fault protection features include overvoltage, overcurrent, and overtemperature protection.
The LTM4623 is RoHS compliant with Pb-free finish.
