LT3791MPFE-1#TRPBF

Overview

The LT3791MPFE-1#TRPBF is a synchronous four-switch buck-boost controller from Analog Devices, designed for high-performance power management. It supports an input voltage range of 4.7 V to 60 V and delivers up to 10 A output current. The device operates with a switching frequency between 200 kHz and 700 kHz and features a quiescent current of 3 mA. It is housed in a 38-pin TSSOP-EP package and functions within a temperature range of -55°C to +150°C.

Feature Summary

Synchronous four-switch architecture enables regulation when input voltage exceeds, equals, or falls below output voltage.
Supports both voltage and current mode control for precise load regulation.
Integrated analog and PWM dimming capabilities for LED driver applications.

Applications

High-power LED lighting systems
Battery-powered equipment requiring wide input ranges
Industrial power supplies

Procurement Notes

Verify the specific suffix 'MPFE-1' against official Analog Devices documentation to confirm military-grade temperature ratings and material compliance. Ensure the '#TRPBF' designation matches the required reel packaging format for surface-mount assembly processes.

Selection Notes

Select this component for designs requiring robust buck-boost operation across extreme input variations. The wide operating temperature range suits harsh environments. Consider thermal performance due to the high current capability and ensure adequate PCB layout for the exposed pad package.

Part Context

This part belongs to the LT3791 family, specialized as a True Color PWM™ LED driver controller. It integrates advanced features for color consistency and brightness control, distinguishing it from standard general-purpose regulators by its focus on lighting application requirements.
