The LTM®4623 is a complete 3A step-down switching mode μModule (micromodule) regulator in a tiny ultrathin 6.25mm×6.25mm×1.82mm LGA and 6.25mm×6.25mm × 2.42mm BGA packages. Included in the package are the switching controller, power FETs, inductor and support components. Operating over an input voltage range of 4V to 20V or 2.375V to 20V with an external bias supply, the LTM4623 supports an output voltage range of 0.6V to 5.5V, set by a single external resistor. Its high efficiency design delivers 3A 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 available with SnPb (BGA) or RoHS compliant terminal finish.
