The LTM4643EY#PBF is a quad DC/DC step-down µModule regulator from Analog Devices Inc., designed for high-density power supply applications. It provides 3A per output channel with a total output current capability up to 12A when outputs are paralleled. The input voltage range is 4V to 20V (2.375V to 20V with external bias), and each output is adjustable from 0.6V to 3.3V via a single resistor. Total output voltage regulation is ±1.5%.
This module integrates switching controllers, power FETs, inductors, and support components in a 9mm × 15mm × 2.42mm 77-BBGA package. It supports surface mount assembly and is suitable for commercial ITE applications. Fault protection includes overvoltage, overcurrent, and overtemperature protection. The device operates over a -40°C to 125°C temperature range and is RoHS3 compliant with SnPb or RoHS compliant terminal finish options.
