CCR230PS3AGEVB 是一款線性 LED 驅動器參考設計，采用安森美半導體恒流調節器 (CCR)。該評估板演示了 DN05047 設計說明中概述的三級并聯串聯拓撲。該評估板還可以進行調整，以模擬 DN05051 設計說明中詳述的三級 120V 并聯串聯電路。驅動器板使用分立晶體管和二極管在并聯和串聯配置之間切換 LED 燈串，以跟蹤整流橋電壓。當使用除 CCR230PS3GEVK LED 評估套件提供的電壓以外的 LED 燈串電壓時，可以更換電阻器以更改切換點。評估板包含一個用于板外 LED 的母連接器，這些 LED 通常安裝在金屬包層板上。

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.
