The LTM4622 is a complete dual 2.5A step-down switching mode µModule(power module) regulator in a miniature ultra-thin 6.25mm × 6.25mm × 1.82mm LGA and 6.25mm × 6.25mm × 2.42mm BGA package. SnPb (BGA) or RoHs-compliant terminal processing is also available. Included in the package are switching controllers, power FETs, inductors and support components.
Typical application diagram
Operating in 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 small number of ceramic input and output capacitors are required.
Pin arrangement
The LTM4622 supports optional burst mode operation and supply track sequencing for output voltage tracking. Its high switching frequency and current mode control enables very fast transient responses to line and load changes without sacrificing stability. The fault protection function includes input overvoltage, output overcurrent, and overtemperature protection
