TDA5051A照明控制演示由一个主控制器和一个从照明控制器。主控制器采用高架板，它由LPC1114的单片机，TDA5051A PLM IC和电源管理电路。交流 - 直流转换器是用来提供13伏直流电源电压。主采用4×PCF8883电容式接近开关，以提供开/关，变得暗淡起来，暗淡了下来，并选择输出遥控照明从控制器。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.
