BALLAST DESIGN
The ballast design incorporates two parts, hardware and software. The ballast controller design portion incorpo-
rates most of the hardware design. The digital design control portion incorporates most of the software design.
Appendix A shows the complete schematic and Appendix B the Bill of Materials.
The Ballast Controller Design
The design of the Ballast control portion of the circuit has been accomplished in International Rectifier’ s Reference
Design IRPLDIM1. Refer to this for waveforms and specific calculations regarding the ballast controller portion of
this design.
Signals of the IR2159
The communication between the microcontroller and the IR21592 is done with four signals, as shown in Fig. 4.
These signals are used for digital dimming (RB3), turning the ballast on or off (RB4), and fault detection (RB5 &
RB6). The microcontroller controls the IR21592 by the following 3 pins: pin SD for shutdown of the IC (active high),
pin FMIN used for fault detection (0 if the IC is
in fault mode) and pin DIM to control the bright-
ness. The microcontroller receives lamp infor-
mation by the signal Lamp-out, connected to
the lamp.
