LT3790IFE#PBF

Overview

The LT3790IFE#PBF is a synchronous four-switch buck-boost controller designed for high-efficiency DC-DC conversion. It supports input voltages from 4.7V to 60V and operates at a fixed switching frequency of 700kHz. The device regulates positive output voltage or current in step-up, step-down, or bypass modes. Packaged in a 38-pin TSSOP with exposed pad, it features integrated synchronous rectification for improved performance in wide input range applications.

Feature Summary

Synchronous four-switch topology enabling seamless transition between buck, boost, and bypass modes
Integrated synchronous rectification drivers to maximize efficiency across wide input voltage ranges
Fixed 700kHz switching frequency for optimized external component size and transient response

Applications

Industrial power supplies requiring wide input voltage ranges
Battery-powered systems needing stable output during discharge cycles
Automotive electronics operating under varying line conditions

Procurement Notes

Verify the specific suffix #PBF confirms lead-free RoHS compliance and tube packaging. Confirm the 38-pin TSSOP-EP package availability matches your assembly requirements. Check current supply status as distribution may vary by region. Ensure design compatibility with the 4.7V to 60V input specification before ordering.

Selection Notes

Select this controller when a single IC must handle both step-up and step-down operations without mode transitions causing instability. The synchronous design reduces external gate drive components compared to non-synchronous alternatives. Consider the 700kHz frequency for balancing EMI and passive component size against switching losses.

Part Context

This component belongs to the LT3790 series of synchronous buck-boost controllers. It complements other Analog Devices power management solutions by providing a versatile topology for applications where input voltage may exceed or fall below the required output level. The family focuses on high efficiency and robust regulation in challenging electrical environments.
