The Analog Devices Inc. LTC3871HLXE-PBF is a PolyPhase® series synchronous buck-boost DC-DC controller designed for high-performance power conversion. This device offers a flexible architecture capable of both step-up and step-down voltage regulation with positive output. Featuring two output phases and a programmable output phase count, it supports advanced control strategies including current limit, enable, frequency control, phase control, and soft start. The switching frequency is adjustable from 60kHz to 460kHz, with a maximum duty cycle of 98%.
The LTC3871HLXE-PBF operates across a wide supply voltage range from 1.2V to 100V and is specified for operation from -40°C to 150°C. Its 48-eLQFP (7x7) package with an exposed pad facilitates efficient thermal management. The controller is suitable for applications requiring high power density and efficiency, including automotive systems, industrial power supplies, and battery charging solutions. It incorporates synchronous rectification for improved efficiency.
