The LTC3874IUFD#TRPBF from Analog Devices is a dual PolyPhase current mode synchronous step-down slave controller. It is designed for high current, multi-phase applications, extending the phase count when paired with a companion master controller. This controller utilizes a unique architecture that enhances the signal-to-noise ratio of the current sense signal, enabling the use of sub-milliohm DCR power inductors for maximum efficiency and reduced switching jitter.
Key electrical specifications include a wide input voltage range of 4.5V to 38V and an output voltage range up to 5.5V. It supports a switching frequency from 250kHz to 1MHz and features dual N-channel MOSFET gate drivers. The device offers accurate phase-to-phase current sharing, even for dynamic loads, and supports programmable features and fault protection when working with a master controller.
This controller is housed in a 28-lead QFN (4x5mm) package with surface mount mounting type. It is suitable for high current distributed power systems, telecom, datacom, and storage systems, as well as intelligent energy-efficient power regulation applications.
