LT3959EFE#PBF

Overview

The LT3959EFE#PBF is a high-performance DC-DC controller from Analog Devices Inc. designed for flexible power conversion topologies including boost, SEPIC, and inverting configurations. It supports an input voltage range of 1.6V to 40V and delivers a switch current capability of 6A. The device features an adjustable switching frequency ranging from 100kHz to 1MHz and operates within a junction temperature range of -40°C to 125°C. Packaged in a 36-WFQFN with a 28-lead exposed pad, it provides a single adjustable output starting at 0.8V.

Feature Summary

Supports multiple converter topologies including boost, SEPIC, and inverting configurations
Capable of handling wide input voltage ranges down to 1.6V
Features adjustable switching frequency for optimized design flexibility

Applications

Battery-powered portable electronics requiring flexible voltage regulation
Automotive systems utilizing varying battery voltages
Industrial equipment needing isolated or inverted power rails

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and temperature grade. Confirm availability status as supply constraints may apply. Ensure compatibility with required thermal management solutions for the QFN package. Cross-reference pinouts with the latest datasheet revision to prevent integration errors during PCB layout.

Selection Notes

Select this component when designing circuits that require topology flexibility beyond standard buck or boost converters. Evaluate the 6A switch current limit against peak load requirements. Consider the 36-pin QFN package for thermal dissipation needs. Verify that the external component selection supports the desired switching frequency range and input voltage conditions.

Part Context

This part belongs to the LT3959 family of wide input voltage range controllers. It is distinct from synchronous buck controllers like the LTC3891 series. The device focuses on non-isolated DC-DC conversion applications where input voltages vary significantly or negative outputs are required.
