OM13314,598: Power Line Lighting Control

Summary

The TDA5051A lighting control demo consists of a master controller and a slave lighting controller. The master controller uses the High-Bay board, which consists of the LPC1114 microcontroller, the TDA5051A PLM IC, and power management circuitry. An AC-DC converter is used to provide +13 V DC supply voltage.

The master employs 4 × PCF8883 capacitive proximity switches to provide On/Off, Dim Up, Dim Down, and Select outputs of the remote lighting slave controller. The slave controller consists of the High-Bay board, an AC-DC converter to provide +13 V supply voltage, and an LED array.

Both the master and the slave are housed in a plastic box with 110 V AC power cords.

The TDA5051A lighting demo board is designed to let customers evaluate the TDA5051A in a realistic application. The demo board includes a the TDA5051A, an LPC1114 microcontroller, a PCA9632 I2C-bus to PWM converter, and software containing some pre-defined functions to brighten and dim the four available LED outputs from the PCA9632. The parameters used by these functions can be easily changed by changing a configuration header file with parameter values used by the pre-defined functions. To further customize the application, the driver functions used in the demo firmware can be easily modified.
