LTC3864HDE#PBF

DC DC Switching Controllers Overview

The LTC3864HDE#PBF is a synchronous step-down DC/DC switching controller manufactured by Analog Devices Inc. It operates with an input voltage range of 3.5V to 60V and supports adjustable output voltages from 600mV to 5.5V. The device features a switchable frequency range between 50kHz and 850kHz, enabling optimization for efficiency or component size. It provides current mode control with cycle-by-cycle current limiting, soft start, and power good indication. The component is housed in a 12-lead MSOP package with an exposed thermal pad and is rated for operation over a junction temperature range of -40°C to 150°C.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix HDE against the official datasheet to confirm the package type and temperature grade match your design requirements. Ensure that the ordering information corresponds to the exact part number variant required for your bill of materials. Cross-reference the manufacturer's latest documentation for any product change notices regarding epoxy or marking updates.

DC DC Switching Controllers Selection Notes

Select this controller when a wide input voltage range up to 60V is required for single-phase buck conversion. The adjustable frequency allows designers to balance electromagnetic interference and passive component size. Consider the thermal performance of the MSOP-EP package for heat dissipation needs in compact layouts.

DC DC Switching Controllers Part Context

This component belongs to the LTC3864 family of synchronous step-down controllers designed for high-efficiency power conversion. It shares architectural similarities with other members like the LTC3863 but is optimized for positive output configurations. The family targets applications requiring robust voltage regulation under varying load and line conditions.

DC DC Switching Controllers Replacement Considerations

Direct replacements include the LTC3864IDE#PBF which offers the same functionality in a DFN package. Designers should verify pin compatibility and thermal characteristics when substituting between MSOP and DFN packages within the same series.
