CCR120PS3AGEVB 是一款線性 LED 驅(qū)動(dòng)器參考設(shè)計(jì)，采用安森美半導(dǎo)體恒流調(diào)節(jié)器 (CCR)。該評(píng)估板演示了 DN05052 設(shè)計(jì)說(shuō)明中概述的兩級(jí)并聯(lián)串聯(lián)拓?fù)洹ｒ?qū)動(dòng)器板使用分立晶體管和二極管在并聯(lián)和串聯(lián)配置之間切換 LED 燈串，以跟蹤整流橋電壓。當(dāng)使用除 CCR120PS3GEVK 評(píng)估套件中提供的 LED 板上提供的電壓以外的 LED 燈串電壓時(shí)，可以更換電阻器以更改切換點(diǎn)。評(píng)估板包含一個(gè)用于板外 LED 的母連接器，這些 LED 通常在金屬包覆板上實(shí)現(xiàn)。

The CCR120PS3AGEVB is a linear LED driver reference design featuring ON Semiconductor Constant Current Regulators (CCRs). This evaluation board demonstrates the Two-Stage, Parallel-to-Series topology, outlined in the DN05052 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 on the LED board provided in the CCR120PS3GEVK evaluation kit. The evaluation board contains a female connector for off-board LEDs, which are typically implemented on a metal-clad board.
