SO-8 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 complete 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.

PIN FUNCTIONS
Pin Name Collector Source diac sec osc Pin Function Collector of the NPN high voltage transistor in the cascode configuration. Low voltage Power MOSFET source in the cascode configuration and GROUND reference. Input of the diac block to start the system up at the beginning. Connection with secondary winding of the voltage transformer, in order to trigger and to supply the device. Output via to charge external capacitor necessary to set the steady state working frequency.
