onsemi Lighting, Ballast Controllers FL7930CMX

The FL7930CMX is a single-stage flyback and boundary-mode power factor correction (PFC) controller designed for lighting applications. It operates in critical conduction mode (CRM) and features a voltage-mode PWM control that eliminates the need for rectified AC line voltage information, reducing power loss. The controller includes multiple protection mechanisms such as over-voltage protection, open-feedback protection, over-current protection, input-voltage-absent detection, and under-voltage lockout. This device is suitable for a variety of applications, including ballast systems, general LED lighting, and industrial, commercial, and residential fixtures. It operates within a temperature range of -40 to +125°C and comes in an 8-lead small outline package (SOP). The FL7930CMX also incorporates an internal soft-start function with overshoot prevention and a total harmonic distortion (THD) optimizer, making it a robust choice for efficient lighting control.
