DC DC Switching Controllers datasheet and documents for LTC3865EUH#PBF

LTC3865EUH#PBF

DC DC Switching Controllers Overview

The LTC3865EUH#PBF is a dual, two-phase synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4.5V to 38V and supports output voltages from 600mV to 5V with up to 25A output current capability. The device features a fixed switching frequency of 770kHz and a typical quiescent current of 30µA. Packaged in a QFN-32 format, it functions as a buck topology regulator controller suitable for surface mount installation across temperatures from -40°C to +125°C.

DC DC Switching Controllers Feature Summary

Dual-channel architecture providing independent control for two-phase synchronous step-down conversion
Pin-selectable output configuration allowing flexible system design integration
Low quiescent current operation extending battery life in portable applications

DC DC Switching Controllers Applications

Distributed power systems requiring dual voltage rails
Industrial equipment power management
Telecommunications infrastructure supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the EU package variant matches your PCB footprint requirements. Ensure the operating temperature grade meets your environmental specifications. Cross-reference the manufacturer part number with official distributor catalogs to validate authenticity and current production status.

DC DC Switching Controllers Selection Notes

Select this component when a dual-output synchronous buck solution is required with pin-configurable outputs. It is appropriate for designs needing a 770kHz switching frequency to balance efficiency and component size. Consider the 38V maximum input rating and 25A current handling capabilities against your load requirements. Verify that the QFN-32 package fits your assembly constraints.

DC DC Switching Controllers Part Context

This part belongs to the LTC3865 series of PolyPhase controllers. It is designed to drive N-channel MOSFETs for high-efficiency power conversion. The device integrates precision error amplifiers and current mode control loops. It is distinct from single-phase or triple-output variants in the broader PMIC portfolio.
