Applications
- Monitor backlighting
- TV backlighting
Procurement Notes
Verify the specific suffix 'J' against the manufacturer's latest datasheet to confirm pinout and electrical characteristics match the design requirements. Confirm moisture sensitivity level (MSL 3) handling procedures are followed during assembly. Ensure the 28-WFQFN bare pad thermal management strategy aligns with the PCB layout guidelines provided in the official documentation.
Selection Notes
Select this component for applications requiring dual-output regulation from a single primary side or integrated solution. It is suitable for designs needing combined constant voltage and constant current outputs. Consider the operating temperature range and package thermal performance when evaluating suitability for enclosed enclosures or high ambient environments compared to other InnoSwitch variants.
Part Context
This part belongs to the InnoSwitch3-MX family, which features PowiGaN technology. The series is designed for efficient, compact power supplies. It combines control, protection, and power switching into a single monolithic IC. This integration reduces external component count and improves reliability for display backlighting applications.
Replacement Considerations
Consult the official Power Integrations substitution guide for verified equivalents. Cross-reference pinouts and electrical parameters before replacing.
