英飞凌（Infineon）正式发布了CDM10V。这款结构紧凑、高度集成的LED调光IC，可让工程师以一个IC替代传统调光方案中的多个分立器件。减少调光电路组件数量和占板空间达70%。英飞凌的CDM10V是业界第一款单芯片照明接口IC，能将0-10V模拟输入转换成主控IC所需的PWM或调光输入信号。该信号是通过光耦进行传输的5mAPWM信号，占空比范围0-100%。
CDM10V可用于多种不同的商业和工业LED照明应用，关键参数可进行一次性配置，比如最小占空比（1-10%）、PWM输出频率（200Hz-2kHz）、调光器/电阻器偏置电流（50μA-500μA）以及“dim-to-off”功能。此外，在启用“dim-to-off”功能的情况下，该IC还可以接受PWM输入。
CDM10采用6引脚的SOT封装，非常适用于高组件密度的小型化PCB设计。Vcc11~25V的供电电压范围，确保兼容常见LED照明应用，包括槽灯、射灯、壁灯、办公室照明和广告灯箱。CDM10V是英飞凌相关照明产品组合的一部分，包括控制IC和MOSFET。

CDM10V产品描述:
CDM10v, the Coolest Dimming solution is a fully integrated 0-10 V dimming interface IC and comes in a 6 pin SOT package to cover space requirements on small PCBs.The device is targeted for various dimming applications in lighting. The IC can be used to transmit analog voltage based signals from a 0-10 V dimmer or potentiometer to the dimming or PWM input of a lighting controller IC in the form of a current based PWM signal to drive an external opto-coupler.
CDM10V replaces many components in a traditional solution and reduces BOM and PCB space significantly. It supports active and passive dimming as well as Dim-to-Off with PWM input possibility. One solution for various applications. The one-time-programming interface allows a wide range of configurations.
