Analog Devices Inc. LTC3875IUH is a high-performance, dual-output step-down DC-DC controller IC. This buck regulator features a wide input voltage range of 4.5V to 38V and a switching frequency adjustable from 250kHz to 720kHz. The LTC3875IUH supports two output phases and is designed for a positive output configuration. Key control features include current limit, enable, frequency control, phase control, power good indication, soft start, and tracking. The device integrates synchronous rectification for improved efficiency. Its robust design and surface mount capability in a 40-QFN (5x5) package make it suitable for demanding applications in industries such as automotive, industrial power, and telecommunications. The operating temperature range is -40°C to 125°C (TJ).
