CCR230PS3AGEVB 是一款线性 LED 驱动器参考设计，采用安森美半导体恒流调节器 (CCR)。该评估板演示了 DN05047 设计说明中概述的三级并联串联拓扑。该评估板还可以进行调整，以模拟 DN05051 设计说明中详述的三级 120V 并联串联电路。驱动器板使用分立晶体管和二极管在并联和串联配置之间切换 LED 灯串，以跟踪整流桥电压。当使用除 CCR230PS3GEVK LED 评估套件提供的电压以外的 LED 灯串电压时，可以更换电阻器以更改切换点。评估板包含一个用于板外 LED 的母连接器，这些 LED 通常安装在金属包层板上。

The CCR230PS3AGEVB is a linear LED driver reference design featuring ON Semiconductor Constant Current Regulators (CCRs). This evaluation board demonstrates the Three-Stage, Parallel-to-Series topology, outlined in the DN05047 design note. This evaluation board can also be adapted to emulate the Three-Stage, 120V Parallel-to-Series circuit detailed in the DN05051 design note. The driver board uses discrete transistors and diodes to switch LED strings between parallel and series configurations to track the rectified bridge voltage. Resistors may be swapped out to change switching points when using LED string voltages other than those provided with the CCR230PS3GEVK LED Evaluation Kit. The evaluation board contains a female connector for off-board LEDs, which are typically implemented on a metal-clad board.
