DC DC Switching Controllers datasheet and documents for LTC3868EUFD-1#PBF

LTC3868EUFD-1#PBF

DC DC Switching Controllers Overview

The LTC3868EUFD-1#PBF is a dual synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4 V to 24 V and supports output voltages from 800 mV to 14 V. The device delivers up to 25 A per channel across two independent outputs. It features a programmable switching frequency adjustable between 75 kHz and 850 kHz. The quiescent current is specified at 170 uA, and load regulation is rated at 0.01%. It functions within a temperature range of -40°C to +85°C and is housed in a QFN-28 package.

DC DC Switching Controllers Feature Summary

Dual-channel architecture providing independent control for two synchronous buck converters
Low quiescent current operation designed for efficient power management
Programmable switching frequency allows optimization for specific design requirements
Integrated shutdown capability for system power control

DC DC Switching Controllers Procurement Notes

Verify component authenticity through authorized distribution channels due to limited supply status. Confirm RoHS compliance documentation matches the specific manufacturing lot. Ensure the QFN-28 package variant aligns with PCB footprint specifications before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this controller when dual isolated or non-isolated low-voltage rails are required from a 4 V to 24 V source. Consider the 25 A per phase current capability and the wide frequency adjustment range for thermal and size optimization. Verify that the 800 mV minimum output voltage meets the target load requirements.

DC DC Switching Controllers Part Context

This component belongs to the LTC3868-1 series of dual synchronous step-down controllers. It is part of Analog Devices' portfolio of power management integrated circuits designed for high-efficiency DC/DC conversion applications requiring precise voltage regulation and multiple output channels.
