• Utilizes average current control method for regulation
• Designed specifically for power factor improvement in single-phase AC systems

Applications

• Power factor correction circuits
• Single-phase AC power supply systems
• Active rectification modules

Procurement Notes

Verify the exact suffix designation upon ordering, as variations such as SY may indicate specific packaging or compliance attributes distinct from standard versions. Confirm RoHS compliance status with the supplier, as historical Sanyo data indicates mixed compliance levels across similar part numbers. Ensure the source document explicitly supports the functional description of average current control for this specific variant before finalizing procurement specifications.

Selection Notes

Select this component when designing single-phase AC power supplies requiring integrated power factor correction. The hybrid construction simplifies thermal management compared to discrete solutions. Verify that the application voltage and current requirements align with the internal power stage capabilities defined in the official datasheet. Consider the SIP package dimensions for PCB layout constraints.

Part Context

This part belongs to the Sanyo STK760 series of active converter hybrid ICs. Similar models like the STK760-213A-E share the same core technology for power factor improvement but may differ in pinout or specific electrical ratings. The series represents Sanyo's approach to integrating complex power management functions into single packages for consumer audio and video equipment power supplies.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Cross-reference with other STK760 variants like the STK760-213A-E only if pin compatibility and electrical parameters are verified against the official schematic. Do not assume interchangeability without checking the specific suffix differences.
