Overview
The Coilcraft ZA9670-BED is a no-opto flyback transformer designed for DC/DC converters, specifically optimized for the Texas Instruments LM25184 chipset. It supports an input voltage range of 4 V to 42 V and delivers a 3.3 V output at 3.5 A, providing 11.55 W of power. The component operates at a switching frequency of 300 kHz. Primary inductance is measured at 300 kHz with 0.1 Vrms and 0 Adc conditions.
Feature Summary
- Optimized for no-opto flyback converter designs using the TI LM25184 chipset
- Provides isolated SMT packaging suitable for surface mount assembly
- Constructed with ferrite core material for efficient magnetic performance
Applications
- Flyback converters
- DC/DC conversion systems
- Power supplies utilizing LM25184 controllers
Procurement Notes
Verify the specific ordering suffix BED against the manufacturer's datasheet to ensure correct packaging configuration. Confirm that the intended application matches the LM25184 chipset requirements. Check RoHS and halogen-free compliance status if required by your manufacturing standards. Ensure the primary voltage range of 4 V to 42 V aligns with your system design parameters before finalizing procurement.
Selection Notes
Select this component when designing a flyback converter around the Texas Instruments LM25184 controller. It is appropriate for applications requiring a 3.3 V output at up to 3.5 A from an input between 4 V and 42 V. Consider the 300 kHz operating frequency and SMT package type during layout planning. This part is one of five versions in the ZA967x series tailored for typical LM25184 design scenarios.
Part Context
The ZA9670-BED belongs to the ZA967x family of no-opto flyback transformers manufactured by Coilcraft. These components are engineered specifically for use with Texas Instruments' LM25184 flyback converter chipset. The family includes multiple output versions, such as ZA9671-BE and ZA9672-BE, to support various design applications within the same controller ecosystem.
Replacement Considerations
Other variants in the ZA967x series, such as ZA9671-BED or ZA9672-BED, may serve as alternatives if different output voltages are required while maintaining compatibility with the LM25184 chipset.
