Analog Devices Inc. LTC3892MPFE-1 is a high-performance, dual-phase synchronous buck controller designed for efficient step-down DC-DC conversion. This device operates from a 4.5V to 60V input supply and features a wide switching frequency range from 105kHz to 835kHz, with specific operational bands between 350kHz and 535kHz. The LTC3892MPFE-1 offers a maximum duty cycle of 99% and supports positive output configurations. Its control features include adjustable current limit, enable functionality, frequency control, power good indication, soft-start, and tracking capabilities. Designed with a 2-phase output configuration, it includes synchronous rectification for enhanced efficiency. The controller is housed in a 28-TSSOP-EP package with an exposed pad for improved thermal performance, suitable for surface mounting. This component is utilized in demanding applications such as automotive power systems, industrial power supplies, and high-reliability computing. The operating temperature range is -55°C to 150°C (TJ).
