LT3959IUHE#PBF

Overview

The LT3959IUHE#PBF is a wide input voltage range boost, SEPIC, and inverting converter manufactured by Analog Devices Inc. It features an adjustable output voltage starting from 0.8V with a maximum switch current of 6A. The device supports a switching frequency range between 100kHz and 1MHz and operates within an input voltage window of 1.6V to 40V. It is housed in a 36-WFQFN package with 28 leads and a bare pad, designed for surface mount installation.

Feature Summary

• Supports boost, SEPIC, and inverting converter topologies
• Wide input voltage range capability
• Adjustable output voltage configuration

Applications

• Positive or negative voltage regulation systems
• Industrial power supply designs
• Automotive electronics applications

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and thermal characteristics. Confirm RoHS compliance status through manufacturer declarations. Ensure the 36-WFQFN package dimensions match your PCB footprint requirements. Validate the 6A switch current rating against your circuit's peak load demands before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring flexible topology options such as SEPIC or inverting configurations. The wide input range accommodates varying source conditions. Ensure adequate thermal management for the QFN package given the 6A current handling capability. Verify that the required switching frequency falls within the specified 100kHz to 1MHz operational window.

Part Context

This part belongs to the LT3959 family of DC-DC converters from Analog Devices. It is distinct from other series like the LT3955 LED drivers or the LTC2959 battery gas gauges found in related product listings. The device serves as a versatile power management solution for converting input voltages across multiple standard topologies.

Replacement Considerations

LT3959EUHE#PBF is documented as a parameter equivalent substitute.
