IMX2370F-TL

Overview

The IMX2370F-TL is a flyback switcher IC from the InnoMux2-EP series by Power Integrations. It supports up to 65 W output with three independent constant voltage outputs and integrated synchronous rectification. The device operates within an input voltage range of 90 VAC to 277 VAC and withstands a breakdown voltage of 750 V. It features a typical isolation rating of 4 kVAC and functions reliably between -40°C and +150°C junction temperature. Packaged in the InSOP-T28D surface-mount format, it utilizes PWM control for precise regulation.

Feature Summary

• Integrates primary-side regulation with synchronous rectification for high efficiency
• Provides three independently regulated constant voltage outputs from a single stage
• Features high-voltage startup and robust protection mechanisms

Applications

• LED backlight drivers requiring multiple voltage rails
• Industrial power supplies with isolated outputs
• Consumer electronics adapters needing compact multi-output designs

Procurement Notes

Verify the specific suffix and tape-and-reel quantity against official distributor catalogs before ordering. Confirm that the InSOP-T28D package dimensions match your PCB footprint requirements. Ensure compliance with RoHS3 standards if required by your manufacturing process. Cross-reference the manufacturer part number with authorized channel listings to avoid counterfeit components.

Selection Notes

Select this component when designing systems requiring three isolated DC outputs without secondary-side controllers. The integrated synchronous rectification reduces thermal stress compared to diode-based solutions. Consider the 750 V drain-source voltage rating for appropriate transformer design. Verify that the input voltage range aligns with global mains specifications.

Part Context

This part belongs to the InnoMux2-EP family, which consolidates AC-DC and DC-DC conversion stages into a single chip. The series targets applications demanding high reliability and reduced bill-of-materials count. Compared to standard flyback controllers, it eliminates the need for optocouplers and secondary error amplifiers.

Replacement Considerations

IMX2378F-TL and IMX2379F-TL are documented parameter-equivalent alternatives within the same series.
