LT3694EFE-1#TRPBF

Overview

The LT3694EFE-1#TRPBF is a monolithic power management IC featuring one synchronous buck converter and two low-dropout linear regulators. It operates with an input voltage range of 4 V to 36 V. The buck regulator delivers up to 2.6 A output current with a programmable switching frequency between 250 kHz and 2.5 MHz. The integrated LDOs provide additional regulated outputs. The device supports shutdown functionality and is housed in a thermally enhanced TSSOP-EP-20 package, suitable for industrial applications operating between -40°C and +125°C.

Feature Summary

• Integrates a high-current synchronous buck converter with dual low-dropout linear regulators on a single chip
• Supports wide input voltage ranges from 4 V to 36 V for flexible power supply designs
• Features adjustable switching frequencies to optimize efficiency and external component size
• Includes shutdown control for system power management

Applications

• Industrial automation systems requiring multiple voltage rails
