Written by: Newton C. Braga
Category: Banco de circuitos

 

El circuito que se muestra en la figura consta de un Módulo Inversor para Lámpara CCFL que se puede alimentar con tensiones de 3.3 V. El circuito es sugerido por Microsemi (www.microsemi). El control de brillo se puede realizar mediante una señal PWM o mediante un potenciómetro. Por potenciómetro, se utiliza el circuito que se muestra en la figura 10. Para este circuito, el módulo ya tiene una resistencia pull-up de 215k ohms. La documentación completa para la preparación de proyectos se puede descargar directamente del sitio web de Microsemi. Otras características que tiene este módulo son el modo de suspensión y una entrada para encender y apagar el módulo desde una señal de comando externa. Hay disponibles otras versiones del mismo módulo para diferentes tensiones de funcionamiento.
