Overview
The INN3996CQ0500-TL is an AC/DC converter from the InnoSwitch3-AQ series, designed for high-efficiency flyback applications. It integrates a 900V primary MOSFET, secondary-side control, and HIPOT-isolated FluxLink feedback. The device supports input voltages from 30 VDC to 550 VDC and delivers up to 20 W of output power. It features multi-mode Quasi-Resonant (QR)/CCM operation and achieves efficiencies up to 95% across the full load range. The component is AEC-Q100 qualified and housed in an InSOP-24D package.
Feature Summary
- Integrates primary controller, 900V switch, and secondary-side sensing with HIPOT-isolated FluxLink feedback
- AEC-Q100 qualified for automotive reliability requirements
- Multi-mode QR/CCM flyback control for high efficiency across load ranges
- Comprehensive protection including over-current, over-voltage, and over-temperature shutdown
Applications
- Automotive auxiliary power supplies
- High-density industrial power converters
- Functional safety critical emergency power systems
Procurement Notes
Verify the specific suffix -TL indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure design compatibility with the InSOP-24D footprint. Check current supply chain availability as distribution may be restricted in certain regions. Validate that the 900V rating meets system voltage requirements.
Selection Notes
Select this component when designing flyback converters requiring 900V blocking capability and automotive qualification. It is suitable for applications needing wide input voltage ranges from 30 VDC to 550 VDC. Choose this IC for designs prioritizing compact size due to its high integration level. Consider it for systems demanding low no-load consumption and high full-load efficiency.
Part Context
This part belongs to the InnoSwitch3-AQ family, which simplifies flyback power converter design by combining primary and secondary controllers into a single IC. The family is characterized by accurate output regulation and integrated safety features. It targets applications requiring high efficiency and compact form factors, particularly in automotive and industrial sectors where reliability is paramount.
Replacement Considerations
Check for other members of the InnoSwitch3-AQ family with different voltage ratings or power levels. Verify pinout and thermal characteristics if substituting with similar Power Integrations devices. Ensure any replacement maintains AEC-Q100 qualification if required for the application.
