MC33260DR2G

Overview

The MC33260DR2G is a Power Factor Correction (PFC) controller manufactured by onsemi, designed for Discontinuous Conduction Mode (DCM) applications. It integrates a PWM controller suitable for offline flyback converters. The device operates in an 8-pin SOIC package and supports surface-mount installation. Key electrical specifications include a supply current of 0.1 mA and compatibility with standard industrial temperature ranges. This component functions as a combined PFC and PWM solution to enhance efficiency in power supply designs.

Feature Summary

• Integrates Power Factor Correction and PWM control functions
• Optimized for Discontinuous Conduction Mode (DCM) operation
• Designed for use in offline flyback converter topologies

Applications

• Offline flyback power supplies
• High-efficiency switching power supplies
• Low-cost AC-DC adapter designs

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with onsemi or authorized distributors before procurement. Confirm that the 8-SOIC package variant matches your PCB footprint requirements. Ensure the DCM control architecture aligns with your target power level and efficiency goals. Cross-reference the part number suffix to confirm tape-and-reel packaging if required for automated assembly processes.

Selection Notes

Select this component when designing cost-effective AC-DC converters requiring integrated PFC and regulation. It is suitable for applications where DCM operation provides sufficient performance without the complexity of continuous mode controllers. Consider the low supply current for standby power optimization. Evaluate thermal management needs based on the SOIC-8 package limitations for higher power densities.

Part Context

The MC33260 belongs to onsemi's portfolio of power management integrated circuits focused on efficient energy conversion. It addresses the need for simplified design architectures in consumer and industrial electronics by combining two control loops into a single chip. This integration reduces component count and board space compared to discrete solutions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult onsemi technical support or official distributor databases for qualified alternatives compatible with DCM PFC flyback designs.
