Description

CDM10V is a fully integrated 0-10 V dimming interface IC and comes in a SOT-23-6 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 5 mA current based PWM signal to drive an external opto-coupler. It replaces many

components in a traditional solution and reduces BOM and PCB space significantly.

The CDM10V IC outputs a 0 - 100 PWM current signal at programmable frequency with an amplitude value of 5

mA.

The duty cycle of the PWM signal can be limited to a dedicated minimum value. Dim-to-off feature is supported

as well and can be enabled on demand.

Embedded digital signal processing maintains minimum variations from device to device.
