- Ultrathin (6.25mm × 6.25mm × 1.82mm) LGA Package and (6.25mm × 6.25mm × 2.42mm) BGA Package
The LTM4623 is a complete 3A step-down switchingmode μModule (micromodule) regulator in a tiny ultrathin6.25mm × 6.25mm × 1.82mm LGA and 6.25mm × 6.25mm× 2.42mm BGA packages. Included in the package are theswitching controller, power FETs, inductor and supportcomponents. Operating over an input voltage range of4V to 20V or 2.375V to 20V with an external bias supply,the LTM4623 supports an output voltage range of 0.6V to5.5V, set by a single external resistor. Its high efficiencydesign delivers 3A continuous output current. Only ceramicinput and output capacitors are needed.
The LTM4623 supports selectable discontinuous modeoperation and output voltage tracking for supply rail sequencing.Its high switching frequency and current modecontrol enable a very fast transient response to line andload changes without sacrificing stability.
Fault protection features include overvoltage, overcurrentand overtemperature protection.
The LTM4623 is available with SnPb (BGA) or RoHScompliant terminal finish.
