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.
