FL7930CM

Overview

The FL7930CM is a single-stage flyback and boundary-mode PFC controller designed for LED lighting applications. It operates in critical conduction mode (CRM) using voltage-mode PWM to generate MOSFET turn-off signals, eliminating the need for input voltage sensing networks. The device features an internal THD optimizer, adjustable output over-voltage protection, and zero-current detection. It supports a supply voltage range of 13 V to 20 V with a maximum operating frequency of 300 kHz. Packaged in an SOP-8 format, it functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates active power factor correction with single-stage flyback topology for simplified LED driver designs
• Utilizes voltage-mode control architecture that removes the requirement for rectified AC line voltage sensing
• Includes internal total harmonic distortion optimization and precise adjustable output over-voltage protection

Applications

• General LED lighting fixtures
• Industrial, commercial, and residential lighting applications
• Outdoor lighting including street, roadway, and parking lot fixtures

Procurement Notes

Verify component authenticity through authorized onsemi distribution channels due to potential availability variations. Confirm package integrity and pin alignment against SOP-8 specifications before integration. Review current lifecycle status as legacy components may have limited long-term supply commitments. Ensure design compatibility with CRM operation requirements and thermal management constraints specified in the official datasheet.

Selection Notes

Select this controller for cost-sensitive LED drivers requiring integrated PFC and flyback conversion. The voltage-mode CRM approach reduces external component count by removing input voltage sensing circuits. Suitable for applications where high efficiency at partial loads is prioritized alongside compact form factors. Evaluate thermal performance requirements given the SOP-8 package limitations and operating temperature range.

Part Context

The FL7930CM belongs to the FL7930C family of power management ICs focused on lighting applications. It represents a specialized solution for boundary-mode PFC controllers that balance performance with simplicity. The component addresses the growing demand for efficient LED drivers in both indoor and outdoor environments while maintaining compliance with power quality standards.

Replacement Considerations

FL7930CMX serves as the tape-and-reel variant of the same functional device. FL7930CM is the tube-packaged version with identical electrical characteristics. Cross-reference with FAN7930 series for CCM PFC alternatives if boundary-mode operation is unsuitable.
