Description
The IRPLDIM1U is a high efficiency, high power factor, dim-
ming electronic ballast designed for driving rapid start fluo-
rescent lamp types. The design contains an EMI filter, ac-
tive power factor correction and a ballast control circuit us-
ing the IR21592. This demo board is intended to ease the
evaluation of the IR21592 Dimming Ballast Control IC,
demonstrate PCB layout techniques and serve as an aid
IR21592 Dimming Ballast Control IC Design Kit
in the development of production ballast's using the IR21592.

Overview
The IRPLDIM1U Demo Board consists of an EMI filter, an active power factor correction front end, a
ballast control section and a resonant lamp output stage. The active power factor correction section
is a boost converter operating in critical conduction mode , free-running frequency mode. The ballast
control section provides frequency modulation control of a traditional RCL lamp resonant output
circuit and is easily adaptable to a wide variety of lamp types. The ballast control section also pro-
vides the necessary circuitry to perform closed-loop dimming, lamp fault detection, shutdown and
auto-restart. All functional descriptions refer to the IRPLDIM1U schematic diagram.

Power Factor Correction
The power factor correction section consists of the L6561D Power Factor Controller IC (IC1), MOSFET
M1, inductor L2, diode D2, capacitor C8 and additional biasing, sensing and compensation compo-
nents (see schematic diagram). This is a boost topology designed to step-up and regulate the output
DC bus voltage while drawing sinusoidal current from the line (low THD) which is "in phase" with the
AC input line voltage (HPF). The design of the power factor correction section was taken from the
L6561D data sheet and information on the operation and design considerations for the L6561D are
contained therein.
Ballast Control
The ballast control section is built around the IR21592 Ballast Control IC, IC2 of the Demo board.
The IR21592 contains an oscillator, a high voltage half-bridge gate driver, an analog dimming inter-
face and lamp fault protection circuitry. A block diagram of the IR21592 IC is shown in figure 1 and a
state diagram of the IR21592 is shown in figure 2.
