LT8316IFE#TRPBF

Overview

The LT8316IFE#TRPBF is a micropower, high-voltage flyback controller from Analog Devices. It operates with an input voltage range of 16V to 600V and supports a switching frequency between 220Hz and 140kHz. The device provides one output phase with synchronous rectification capability. It is housed in a TSSOP-20 package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Eliminates the need for opto-isolators by sampling output voltage directly from the primary side.
• Supports synchronous rectification for improved efficiency in isolated flyback topologies.
• Integrates current limit, enable, and soft start control features.

Applications

• Isolated power supplies requiring no opto-isolation
• High-voltage flyback converter designs
• Micropower industrial control systems

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm that the specific suffix matches the required tape and reel packaging specifications. Ensure compliance with RoHS directives and check for any regional distribution restrictions prior to finalizing procurement orders.

Selection Notes

Select this controller for applications demanding high input voltages up to 600V without opto-isolator complexity. Consider the TSSOP-20 package constraints and thermal management requirements for the specified operating temperature range. Evaluate the 140kHz maximum switching frequency against system size and efficiency targets.

Part Context

This component belongs to the LT8316 series of micropower flyback controllers. It is designed to simplify isolated power supply designs by removing the feedback loop isolation barrier.
