SG6980DDZ

Overview

The SG6980DDZ is a highly integrated AC-DC controller designed for boost power-factor-correction (PFC) applications. It operates with a switching frequency of 65kHz and supports a supply voltage range of 12.5V to 20V. The device features a low startup current of 10 µA and functions within an operating temperature range of -20°C to 125°C. Packaged in a 16-PDIP through-hole configuration, it requires minimal external components to achieve efficient power factor correction.

Feature Summary

• Highly integrated design requiring very few external components
• Low startup current consumption of 10 µA
• Optimized for boost power-factor-correction topologies

Applications

• Power supplies with boost power-factor-correction
• AC-DC conversion systems

Procurement Notes

Verify the manufacturer origin as Fairchild Semiconductor was acquired by ON Semiconductor. Confirm the specific package type matches the required 16-PDIP through-hole form factor. Ensure the component meets the specified electrical parameters for PFC controller functionality before integration into the design.

Selection Notes

Select this component for designs requiring a simplified PFC implementation with reduced external part count. The low startup current aids in efficiency optimization. Ensure the application environment stays within the -20°C to 125°C operating temperature range and utilizes the appropriate 16-pin DIP mounting style.

Part Context

This component belongs to the SG6980 series of power management ICs originally developed by Fairchild Semiconductor. Following the acquisition of Fairchild by ON Semiconductor, these parts are now distributed under the ON Semiconductor brand while retaining their original functional specifications and pinouts.

Replacement Considerations

Check for direct equivalents from ON Semiconductor or other manufacturers offering compatible 65kHz PFC controllers in 16-PDIP packages. Verify that substitute parts maintain the same supply voltage range and startup current characteristics.
