Included in the package are the switching control- lers, power FETs, inductors and support components. Operating over an input voltage range of 3.1V to 20V, the LTM4671 supports an output voltage range of 0.6V to 3.3V for two 12A channels and 0.6V to 5.5V for two 5A channels, each set by a single external resistor. Only bulk input and output capacitors are needed. Fault protection features include overvoltage, overcurrent and overtemperature protection. The LTM4671 is offered in 9.5mm × 16mm × 4.72mm BGA package.
