DESCRIPTION

The VK05CFL is a monolithic device housed in a

standard

STMicroelectronics

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

using

Diac

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.
