L6520TR

Lighting, Ballast Controllers Overview

The L6520TR is a CFL/TL controller manufactured by STMicroelectronics, designed for electronic lamp ballast applications. It operates within a frequency range of 46kHz to 47.2kHz and requires a supply voltage between 10.5V and 18.5V. The device draws a typical supply current of 8 mA and functions reliably across an operating temperature range of -25°C to 85°C. Packaged in an 8-SOIC format with dimensions of 0.154 inches (3.90mm) width, it is supplied in tape and reel packaging.
