FL7930BM

Overview

The FL7930BM is a single-stage flyback and boundary-mode PFC controller designed for LED lighting applications. It integrates a CRM PFC controller with a secondary-side regulation mechanism to eliminate the need for an optocoupler. The device operates from a supply voltage range of 13 V to 20 V and supports a switching frequency up to 300 kHz. It is housed in an SOP-8 package and functions within a temperature range of -40 °C to +125 °C.

Feature Summary

Integrates boundary-mode PFC control with secondary-side regulation for simplified design
Eliminates the requirement for an optocoupler through isolated feedback sensing
Includes soft-start functionality to manage inrush current during startup

Applications

Single-stage flyback LED drivers for general lighting
LED street lighting power supplies
High-power-factor LED ballasts

Procurement Notes

Verify the specific suffix (e.g., BM, BMX) against the manufacturer's datasheet to confirm pinout and packaging compatibility. Ensure the component meets RoHS requirements if applicable to your region. Confirm availability status as some variants may be discontinued or subject to long lead times.

Selection Notes

Select this component for designs requiring high power factor correction without complex primary-side control loops. It is suitable for applications where eliminating the optocoupler improves reliability and reduces component count. Verify that the input voltage range and output power requirements align with the controller's capabilities.

Part Context

This part belongs to the FL7930 family of single-stage controllers by onsemi. It is functionally related to the FAN7930 series but optimized specifically for LED lighting applications using secondary-side regulation. The FL7930B variant is often used in reference designs for 150W to 160W LED systems.
