L6569 Electronic Ballast
![](https://freecircuitdiagram.com/wp-content/uploads/2010/04/L6569-Electronic-Ballast.gif)
This is a electronic ballast circuit using L6569. This circuit uses The L6569 because it can control a low voltage halogen lamp transformer or a symmetric half bridge inverter of a fluorescent lamp ballast directly. The prevention of cross conduction is done by Two 270mA buffers drive the inverter MOSFETs with a 1.25ms built-in dead time. This circuit need only […]
