Texas Instruments LP5907 | Demoboard TIDA01415
100-W, High-Res 16-bit Color-Tunable, 0.15% Dimmable RGBW LED Driver Ref Design
Overview
| Topology | Other Topology |
| IC revision | E1 |
Description
The TIDA-01415 design is a full color tunable LED Driver suitable for applications such as stage and architectural lights. This TI Design supports three different LED current control methods such as analog, PWM-based enable and disable of buck current controller, and PWM-based shunting of LED using a MOSFET across the LED. This TI Design demonstrates the finest range of individual RGBW LED strings color control and enables development of highly efficient DC-DC LED luminaires capable of wide color gamut generation with trillions of colors while at the same time being imperceptible to high-end cameras and video broadcast equipment.
Features
- Four buck current controllers driving RGBW LED strings at 30V and string current of up to 0.75A (also tested up to 1.25A)
- LED buck current controllers efficiency exceeding 96% at full load with maximum operating frequency up-to 600 kHz
- 100% to 0.2% Contrast setting for PWM dimming method at 30 and 50 kHz
- 100% to 0.15% Contrast setting and better Linearity for Shunt dimming mode at 30 and 50 kHz
- High-resolution PWM feature of C2000™ with 180-ps step enables current adjustment with resolution > 16 bits for both PWM and Shunt FET methods even at 50kHz dimming frequency
- 4Ch, 12bit DAC used for IADJ setting of individual LED strings to enable analog dimming
Typical applications
- Stage Lighting, Indoor and Outdoor LED Architecture Lightinig, Full colour tunable indoor Luminare for educational and health care applications
- Wall Washers
