FAN6961CSY

Overview

The FAN6961CSY is a Green mode PFC forward PWM controller manufactured by onsemi. It operates in boundary conduction mode (BCM) with a switching frequency of 60kHz. The device supports a maximum operating supply voltage of 24.5V and functions within a temperature range of -40°C to +125°C. It utilizes an 8-pin SOIC surface-mount package. Key electrical characteristics include a startup supply current of 20µA, a maximum source current of 800µA, and a maximum reverse current of 20µA.

Feature Summary

Implements Green mode technology for high-efficiency power factor correction
Operates in boundary conduction mode (BCM) for reduced switching losses
Integrates zero-power detection capabilities
Supports wide input voltage ranges up to 24.5V

Applications

High-efficiency power factor correction stages
Power management systems requiring low standby power
Industrial power supplies
Consumer electronics power adapters

Procurement Notes

Verify the specific suffix 'CSY' against official onsemi documentation to confirm pinout and functional compatibility with existing designs. Confirm RoHS compliance status through the manufacturer's datasheet or certification documents before integration. Ensure the 8-SOIC package dimensions match the target PCB footprint requirements.

Selection Notes

Select this component for applications requiring boundary conduction mode control with integrated Green mode features. The 8-SOIC package suits surface-mount assembly processes. Verify that the 60kHz switching frequency aligns with electromagnetic interference constraints. Ensure the 24.5V maximum supply voltage covers the system's operational range.

Part Context

The FAN6961CSY belongs to the FAN6961 series of power factor correction controllers from onsemi. This series focuses on improving efficiency in AC-DC conversion systems. The CSY suffix typically denotes the specific package type and tape/reel configuration for surface-mount manufacturing.

Replacement Considerations

Consult onsemi official substitution guides for verified alternatives. Cross-reference pinouts and electrical specifications carefully when considering equivalent parts from other manufacturers.
