CDM10V, the Coolest Dimming solution is a fully integrated 0V to 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 0V to 10V 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.
