The LTM®4622 is a complete dual 2.5A step-down switching mode μModule® (powermodule) 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 3.6V to 20V, the LTM4622 supports an output
voltage range of 0.6V to 5.5V, set by a single external
resistor. Its high efficiency design delivers dual 2.5A continuous, 3A peak, output current. Only a few ceramic input
and output capacitors are needed.
The LTM4622 supports selectable Burst 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 input overvoltage, output
overcurrent and overtemperature protection.
The LTM4622 is available with SnPb (BGA) or RoHS compliant terminal finish.
