The STEVAL-ILB004V1 demonstration board is an electronic ballast that adds “intelligence” to ballast circuits, thanks to the use of a microcontroller. It can drive many different lamp groups and is capable of recognizing T5-type fluorescent lamps with power ratings of 24W, 39W, 54W, and 80W. The board consists of a boost converter (power factor controller) and an inverter in a half-bridge configuration. Both stages are controlled by the ST7LIT19BF1 microcontroller, which provides signals to the L6382D5 power management unit and the STP5NK60Z power MOSFET. After tube recognition, the system sets the parameters to drive the lamp correctly.
