Description

The STEVAL-ILB004V1 demonstration board is

an electronic ballast that adds “intelligence” to

ballast circuits, thanks to the use of a

microcontroller. Rather than having a dedicated

circuit for each tube lamp with a single ballast, the

STEVAL-ILB004V1 can drive many different lamp

groups. The system is capable of recognizing T5-

type fluorescent lamps, with power ratings of 24

W, 39 W, 54 W and 80 W. It consists of two main

blocks: a boost converter (power factor controller)

working in transition mode (fixed TON and

variable frequency), and an inverter in half-bridge

configuration working in zero-voltage switching.

Both the ballast and PFC stages are controlled by

the ST7LIT19BF1 microcontroller, which provides

its signal to the L6382D5 power management

unit. The power management unit delivers the

right voltage and current levels to the

STP5NK60Z power MOSFET. After tube

recognition, the system sets the parameters to

drive the lamp correctly.
