Overview
The FAN6921MLMY is an integrated Critical Mode PFC and Quasi-Resonant Current Mode PWM Controller manufactured by onsemi. It combines a BCM Boost PFC stage with a Flyback-QR topology in a single chip, designed for high-efficiency AC to DC power conversion. The device supports input voltages from 90V to 264V AC and is suitable for applications requiring outputs such as 19V at 4.74A (90W). It operates within a temperature range of -40°C to +105°C and utilizes an SOP-16 package.
Feature Summary
- Integrates Critical Mode Power Factor Correction (PFC) and Quasi-Resonant Current Mode PWM control functions into a single controller.
- Supports BCM Boost PFC topology combined with Flyback-QR secondary side regulation for efficient power conversion.
- Designed for wide-range AC input voltage operation suitable for universal adapter applications.
Applications
- AC to DC adapters
- Single output power supplies
- High-efficiency power factor correction systems
Procurement Notes
Verify the specific suffix 'MLMY' against official datasheets to confirm pinout and thermal characteristics, as variations exist within the FAN6921 family. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements prior to assembly. Ensure the supplier provides valid traceability documentation for this component.
Selection Notes
Select this component for designs requiring integrated PFC and PWM control to reduce bill of materials and board space. It is appropriate for medium-power adapter applications around 90W. Consider the operating temperature range and package type when evaluating thermal management solutions for the final enclosure design.
Part Context
The FAN6921 series includes variants like FAN6921BMR and FAN6920MRMY, all serving as integrated controllers for power factor correction and PWM generation. These devices are part of onsemi's portfolio for managing efficient AC-DC conversion topologies, specifically targeting critical mode boost and quasi-resonant flyback applications.
Replacement Considerations
Consult official substitution guides for direct replacements. Variants such as FAN6921BMR or FAN6921ML may offer functional compatibility but require verification of package dimensions and electrical parameter alignment before implementation.
