Overview
The IMX2379F-TL is a flyback switcher IC from the InnoMux2-EP series by Power Integrations. It provides three independent constant voltage outputs with a total power capability of 65 W and supports a 750 V breakdown voltage. The device integrates AC-DC and DC-DC conversion stages into a single chip, utilizing PowiGaN technology for high efficiency. It operates within an ambient temperature range of -40°C to +150°C and is housed in an InSOP-T28D surface-mount package.
Feature Summary
- Integrates AC-DC and downstream DC-DC conversion stages into a single chip to minimize component count
- Provides up to three independently regulated constant voltage outputs
- Utilizes PowiGaN technology with zero-voltage switching and synchronous rectification
Applications
- White home appliances requiring multiple internal voltages
- Industrial systems with diverse power requirements
- Monitor backlights and internal battery charging circuits
Procurement Notes
Verify the specific suffix TL against official datasheets to confirm reel packaging specifications. Ensure compatibility with InSOP-T28D footprint designs. Cross-reference thermal management requirements with the manufacturer's application notes for optimal heat dissipation without external heatsinks.
Selection Notes
Select this component for designs requiring three isolated outputs without secondary DC-DC converters. Evaluate the 65 W power limit against peak load demands. Confirm that the 750 V rating suits the primary side stress conditions. Consider the InnoMux2-EP series benefits for reducing PCB area and improving overall system efficiency.
Part Context
This part belongs to the InnoMux2-EP family, designed for single-stage multi-output offline power supplies. It replaces traditional two-stage architectures by combining primary-side control with integrated secondary regulation capabilities. The series targets applications needing compact, efficient power solutions with minimal external components.
Replacement Considerations
IMX2378F-TL offers similar functionality with 55 W capacity. IMX2279F-TL provides 70 W with one constant current output. Verify pinout and electrical parameters before substitution.
