NXP Semiconductors TDA5051A
Lighting Master-Slave Demo Board

NXP Semiconductors TDA5051A Lighting Master-Slave Demo Board 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 +13V 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 +13V supply voltage, and an LED array. For the NXP Semiconductors TDA5051A Lighting Master-Slave Demo Board, both the master and slave controllers are housed in a plastic box with 110V AC power cords.
