Rutronik adds Infineon’s digital PMW converter
Designed for dimming applications in lighting, the CDM10V 0 to 10V dimming interface IC from Infineon, is now available from distributor, Rutronik.
The IC comes in a small, 6pin SOT23 package to cover space requirements on small PCBs. It can be used to transmit analogue voltage based signals from a 0 to 10V dimmer or potentiometer to the dimming or PWM input of a lighting controller IC in the form of a current-based PWW signal to drive an external optocoupler. It can replace components in a traditional lighting control design, and is claimed to reduce bill of materials and PCB space significantly. Active and passive dimming is supported as well as the possibility for dim-to-off with PWM input and configurable PWM frequency from 200 to 2,000Hz. The configurable R-DIM bias current is 50 to 500microA. It has a supply voltage range from 11 up to 25V. The dimming device can be used as the one-time-programming interface and the embedded digital signal processing maintains minimum variations from device to device, says the company.
