VK05CFL
DESCRIPTION
The VK05CFL is a monolithic device housed in a standard SO-8 package, made by using STMicroelectronics proprietary VIPower M3 Technology. This device is intended both for the low side and the high side driver in half bridge CFL applications. This means that it is possible to realize a plete H-bridge by using two VK05CFL devices: one connected in HSD configuration and the other connected in LSD configuration. In the VK05CFL used in HSD BLOCK DIAGRAM configuration, the diac pin must be connected to source pin. Both diac functionality and discharge circuit for external diac capacitor are integrated. By an external capacitor it is possible to choose the nominal working frequency without influence on the ignition one.
