IDC2000 ICs for Ballast Controllers

IDC2000 ICs integrate all the functions of low-cost, high performance networkable electronic ballasts into one single chip. IDC2000 ICs provide all of the control and protection functions required by the ballast and lamps, as well as an embedded PLC modem for communications.

Prolonging Lamp Life and Saving Energy

Customizable parameters for driving lamps include:

1. Preheat parameters - pulse regime and time parameters
2. Ignition parameters - pulse regime, light level, fade, PID gains
3. Lighting parameters - pulse regime, light level, fade, PID gains
4. DC Bus parameters - operation, limits and protection levels
5. PFC stage parameters - pulse regime, PID gains
6. Protection parameters - levels for lamp over and under voltage, lamp end of life, time between start-ups, etc.

IDC2000 Features for Lighting Controls

Feature	Design Advantage
Low Cost	Simplified power topologies, integration of the communication function in the ASIC controller and smart control algorithms, dramatically reduce component count, the need of component accuracy and material cost.
Fast Time to Market	GUI design tools created for the IDC2000 configuration allow each customer to incorporate proprietary control algorithms, power topology and lamp type, adjusting and tuning the ballast in a few days, all w/o code programming.
Development Effort/Cost	Allows the designer to create a ballast with the highest performances and lamp life parameters at all light levels using a common ballast hardware platform.
Remote Control Options	Embedded Power Line Carrier Modem, RF interface and other standard (I2C) communication interfaces enabling many of the remote control options desired in the market.
Common Hardware Platform	The IDC2000 does all the performance variations by means of programming the silicon logic using a GUI tool. No need of components to adjust and tune the ballast.
Available Design Tools	The PDK3 and demo board kits provide the designer easy to follow and rapid support to working ballast systems that meet their companies unique specifications.
Individual Lamp Protection	Individual, separate control, command and protection of each lamp or group of lamps in a light fixture.
Flexible Lamp Control	Allows the implementation of a ballast driving a multiplicity of lamps working in parallel, each one individually controlled and protected. Different types of lamps working in parallel at their best operating conditions and controlled by the same controller.
Multi-Fixture Ballast	Provides a low cost, high performance multi-fixture (central) ballast, allowing each fixture to use a different type of lamp with separate control for dimming, shutdown and protection and providing equal light levels for fixtures installed at different distances.
Emergency Operation	Combines common ballast operation with emergency function with smart battery management.
Energy Savings	IDC2000 allows excellent BEF at low light levels. Separate lamp control allows further savings by individual shutdown of lamps instead of using dimming. Network Systems features can be added by easily connecting occupancy and analog light sensors, etc. directly to the IDC2000.
Load Shedding	Allows load shedding by dimming or shutting down individual lamps in each fixture.
Power Factor Correction	Embedded digital PFC configurable to the most advantageous power topology enabling lower THD at every light level.
Control Options	Allows selection from a library of different methods of dimming: PWM, FM, Phase Control, etc. or a combination thereof – or the customization of the designer's proprietary solution.

Controlling LEDs with the IDC2000

Warm White Light Achieved by: Independently Driven Four Color LED Array with Individual Current; Light and LED Temperature Feedbacks.

IDC2000 Capabilities for LEDs

1. Simultaneous control of different modules:
   1. Independent control of up to 9 LED fixture driver
   2. Control of PFC module (continuous / discontinuous mode)
   3. Control of battery charger and back up supply
2. Adjustment of control system for different power topologies (buck buck-boost, etc.) and various control schemes (continuous current mode, peak current mode).
3. Closed loop control of LEDs current (LEDs light output) as function of LED junction temperature.
4. Realization of the multi parametric control algorithms to achieve efficient dimming without spectral shift of the light. Modes are modified on-the-fly during the entire dimming range like continuous current at high light level, changing to PWM at lower light levels.
   1. PWM mode (low light level)
   2. Mixed algorithm (medium light level)
   3. Full continuous mode (high light level)
5. It is possible to increase the switching frequency in the range of 200 - 1500kHz to reduce ripple current and power efficiency.
6. Flexible system adjustment for different LEDs parameters:
1. light vs. current
2. light vs. temperature
3. forward current vs. voltage and temperature
7. External interface can be realized by means of power line only (on-chip Power Line Carrier modem)
8. Compatibility with high frequency power stage (fsw up to 1.5MHz)to reduce cost/size of magnetic and ripple of LEDs current
9. Capability to programmed lighting scheme for regular and emergency lighting
