Introduction

TS19751BCS is a versatile RGB LED driver chip with integrated single stage mains-direct drive featuring an on-board full-sin PWM dimming and adjustable current output. It allows the user to control each of the three LEDs respectively, either through the I2C interface or through its three dedicated control pins. This allows for higher color accuracy and improved overall lighting effect. Furthermore, it also provides exceptional flexibility with adjustable current output through the on-chip PRISM technology, making TS19751BCS the ideal candidate for full color LED applications.

TS19751BCS RLG application field

The TS19751BCS is suitable for both indoor and outdoor LED lighting applications. For indoor applications, it can be used to control LED strips or LED light bulbs, while for outdoors, it can be used to control LED floodlights. It is capable of supporting any type of LED light such as RGB, RGBW and dye-sublimation light sources, giving the user great control over the color palette and light level. Furthermore, the TS19751BCS chip is also well suited for automotive headlight applications.

TS19751BCS RLG working principle

The TS19751BCS RLG is an integrated converter that allows for direct connection of the LEDs to mains power. The single stage converter used in TS19751BCS RLG makes it incredibly efficient in power conversion, with a typical efficiency of up to 94%. It also features an on-chip dual-loop full- sin PWM dimming controller, with an adjustable frequency range of 20kHz to 250kHz, allowing for excellent dimming control at the highest efficiency.

In terms of the current output, the TS19751BCS RLG chip features an on-chip PRISM technology that allows for digital adjustable current output through its I2C interface or dedicated control pins. This allows the user to set the output current of each of the three LEDs independently and gives unparalleled control over the light effect and color accuracy. Furthermore, the chip also comes with an adjustable over-temperature protection ensuring the safe operation of the system at all times.

Conclusion

The TS19751BCS RLG chip is a highly efficient and versatile LED driver that provides exceptional control over the light level and color accuracy. Through the on-chip full-sin PWM dimming and PRISM technology, it can support any type of LED light source, making it ideal for indoor and outdoor LED lighting, as well as automotive headlight applications.
