EVAL6574B Detalles de producto

Description
This design was developed to drive a TL fluorescent lamp of up to 58 W. It is composed of two sections: the PFC using the L6561 controller, and the ballast based on the L6574. The application includes a current feedback that can be used to control the power (and, if necessary, the dimming function) by varying the switching frequency during normal lamp operation. The application also features safety circuitry which activates when an open load or faulty lamp ignition is detected. The PFC pre-regulator allows connection of the application to a wide input voltage range (85 Vac to 265 Vac) providing a Power Factor higher than 0.99 and a THD lower than 10%. EVAL6574B
