YA9036-ALD

Overview

The Coilcraft YA9036-ALD is a surface-mount no-opto flyback transformer designed for isolated DC/DC converter applications. It features 1500 Vrms isolation and supports input voltages from 4 V to 65 V, delivering 24 V at 0.25 A (6 W) with a switching frequency of 300 kHz. The component utilizes ferrite core material and is optimized specifically for use with Texas Instruments LM5180 and LM25180 controllers.

Feature Summary

• Optimized for no-optocoupler flyback converter topologies
• Provides 1500 Vrms electrical isolation
• Designed for surface-mount assembly

Applications

• LM5180-based flyback converters
• LM25180-based flyback converters
• Isolated DC/DC power supplies

Procurement Notes

Verify the specific suffix (e.g., -ALD) against the manufacturer's current datasheet to ensure correct pinout and packaging configuration. Confirm that the intended application aligns with the specified isolation voltage and thermal limits. Cross-reference the primary inductance requirements with the target controller specifications before finalizing the design.

Selection Notes

Select this component when designing isolated power stages using TI LM5180 or LM25180 controllers requiring no optocoupler feedback. Ensure the system operates within the 4 V to 65 V input range and requires 1500 Vrms isolation. Verify that the 300 kHz switching frequency matches the controller settings and that the 6 W output power meets the load requirements.

Part Context

This part belongs to Coilcraft's No-Opto Flyback Transformer series, which eliminates the need for optocouplers by utilizing auxiliary winding feedback. These transformers are engineered for high reliability and compact designs in isolated power conversion systems.

Replacement Considerations

Direct substitutes include other parts from the YA903x-AL family, such as the YA9037-ALD, provided the output voltage and current ratings match the design requirements. Verify compatibility with the specific controller IC.
