IMX2278F-TL

Overview

The IMX2278F-TL is a flyback switcher IC from the InnoMux2-EP series, designed for AC/DC conversion with a 60 W power rating. It features a 750V drain voltage capability and supports one constant voltage (CV) and one constant current (CC) output channel. The device integrates synchronous rectification (SR) to enhance efficiency. It operates within an input voltage range of 90 V to 277 V and functions across a temperature range of -40°C to +150°C. The component is housed in an InSOP-T28D surface-mount package.

Feature Summary

• Integrates synchronous rectification for improved converter efficiency
• Supports combined constant voltage and constant current output regulation
• High breakdown voltage design suitable for universal input applications

Applications

• LED lighting drivers requiring precise current regulation
• Battery chargers with combined voltage and current control
• General-purpose AC/DC adapters

Procurement Notes

Verify the specific suffix 'TL' against official Power Integrations documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with InSOP-T28D footprint designs. Check for moisture sensitivity level requirements during storage and handling. Confirm RoHS compliance status through the manufacturer's latest datasheet or product compliance database before finalizing procurement.

Selection Notes

Select this component when designing converters requiring simultaneous CV and CC regulation at approximately 60 W. The integrated SR reduces external component count and thermal management needs. Verify that the application input voltage falls within the specified 90 V to 277 V range. Ensure the PCB layout supports the InSOP-T28D package dimensions and thermal dissipation requirements for high-temperature operation up to 150°C.

Part Context
