The Analog Devices Inc. LTC3807MPUDC-TRPBF is a high-performance, 38V synchronous buck controller designed for step-down DC-DC conversion. This component features a transistor driver output and supports a single positive output phase. With a wide input voltage range from 4V to 38V and a switching frequency adjustable from 50kHz to 900kHz, it offers flexibility for various power supply designs. Key control features include current limit, enable, frequency control, soft start, and tracking, enabling precise management of the power conversion process. The device operates efficiently with a maximum duty cycle of 99% and a synchronous rectifier for enhanced performance. Its robust design is suitable for demanding applications across industrial, automotive, and telecommunications sectors. The LTC3807MPUDC-TRPBF is supplied in a 20-QFN (3x4) exposed pad package, presented on a tape and reel for surface mount assembly. The extended operating temperature range of -55°C to 150°C (TJ) ensures reliability in harsh environments.
