LT3688EUF#TRPBF

Overview

The LT3688EUF#TRPBF is a dual-channel synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.8 V to 36 V and withstands transients up to 60 V. Each channel provides an adjustable output voltage from 0.8 V to 32.4 V with a maximum current of 800 mA. The device integrates two power-on reset timers, a watchdog timer, and a shutdown pin. It utilizes a fixed 2.2 MHz switching frequency and features a QFN-24 package for surface mount installation.

Feature Summary

Dual-channel synchronous buck topology providing independent adjustable outputs
Integrated dual power-on reset generators and a watchdog timer for system protection
High input voltage tolerance supporting wide-range industrial supply rails

Applications

Industrial control systems requiring isolated or non-isolated dual rail generation
Portable instrumentation powered by single-cell lithium batteries
Embedded systems utilizing microcontrollers needing stable regulated voltages

Procurement Notes

Verify the suffix #TRPBF indicates tape-and-reel packaging distinct from tube variants. Confirm the EUF package designation matches the required footprint. Ensure the component meets RoHS compliance standards for your specific manufacturing region before finalizing procurement orders.

Selection Notes

Select this component when dual low-current rails are needed from a high-voltage source. The integrated resets simplify board design by removing external logic. Verify thermal requirements for the QFN-24 package under maximum load conditions in enclosed environments.

Part Context

This part belongs to the LT3688 family of dual synchronous buck regulators. It shares functional similarities with other Analog Devices PMICs but is distinguished by its specific combination of high input voltage capability and integrated timing protection features within a compact form factor.
