LT8316IFE#WTRPBF

Overview

The LT8316IFE#WTRPBF is a micropower, high-voltage flyback controller manufactured by Analog Devices Inc. It operates with an input voltage range of 16V to 560V and supports a maximum input of 600V. The device utilizes a TSSOP-20 package and functions within a temperature range of -40°C to +125°C. Switching frequency ranges from 3.5 kHz to 140 kHz. It provides constant-current and constant-voltage regulation without requiring an opto-isolator. Output power capability reaches up to 100 W, with output currents ranging from 30 mA to 4 A and a typical output voltage of 12 V.

Feature Summary

Eliminates the need for an opto-isolator by sampling output voltage directly from the secondary side for regulation.
Supports wide input voltage ranges from 16V to 560V, accommodating high-voltage applications.
Features low quiescent current and low-ripple light load Burst Mode operation for enhanced efficiency.

Applications

High-voltage isolated power supplies
Industrial control systems
Battery chargers

Procurement Notes

Verify the specific suffix 'WTRPBF' against official Analog Devices documentation to confirm tape-and-reel packaging and exact electrical tolerances. Ensure compatibility with your PCB footprint for the TSSOP-20 package. Cross-reference the manufacturer's latest datasheet revision for any updates on thermal characteristics or recommended external component values.

Selection Notes

Select this component when designing isolated flyback converters that require high input voltage tolerance without opto-isolators. Consider the 16V to 560V input range and the 100 W power capability. Evaluate the switching frequency requirements against the 3.5 kHz to 140 kHz operational window. Confirm that the TSSOP-20 package fits the design constraints.

Part Context

This part belongs to the LT8316 series of micropower flyback controllers. It shares core functionalities with other variants in the family, such as the LT8316IFE#PBF, but differs in packaging and reel specifications. The series is designed for high-efficiency, high-voltage isolated power conversion applications.
