MC33260DG

Overview

The MC33260DG is a GreenLine compact power factor controller designed for discontinuous conduction mode (DCM) applications. It operates within a supply voltage range of 7V to 36V and supports a maximum operating temperature of 105°C. The device features a low start-up current of 0.25mA and includes zero-power detection capabilities. Packaged in an 8-pin SOIC format, it integrates essential control functions for electronic ballasts and offline power supplies.

Feature Summary

• Integrated zero-power detection for enhanced efficiency at light loads
• Compact design optimized for space-constrained electronic ballast applications
• Supports discontinuous conduction mode operation for simplified circuit implementation

Applications

• Electronic ballasts meeting international standard requirements
• Offline power supplies
• Power factor correction preconverters

Procurement Notes

Verify the specific package variant against the datasheet, as the MC33260 series includes both PDIP and SOIC options. Confirm that the DG suffix corresponds to the required surface-mount configuration. Ensure compatibility with the target application's thermal and electrical specifications before finalizing procurement.

Selection Notes

Select this component for applications requiring DCM PFC control in compact form factors. It is suitable for designs where low start-up current and integrated zero-power detection are prioritized. Verify that the 8-pin SOIC package meets the PCB layout constraints and thermal management requirements of the specific system design.

Part Context

Part of the onsemi GreenLine family, the MC33260 series focuses on cost-effective and compact power factor correction solutions. The MC33260DG specifically denotes the surface-mount variant, distinguishing it from through-hole packages like the PG suffix. This series targets compliance with international standards for lighting and power supply applications.

Replacement Considerations

Check for direct pin-compatible alternatives within the MC33260 family, such as the MC33260PG for through-hole mounting. Verify functional equivalence regarding control logic and electrical limits when considering cross-package substitutions.
