CDM10VD is a fully integrated 0-10V dimming interface IC and comes in a 6pin SOT package to cover space requirements on small PCBs. The device is coming in 4 different variants with different feature sets. The CDM10VD family is targeted for various dimming applications in lighting which requires dim-to-off. The IC can be used to transmit analog voltage-based signals from a 0-10V 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.
CDM10VD replaces many components in a traditional solution and reduces BOM and PCB space significantly. It supports active, passive and PWM dimming in applications with DIM-to-Off requirements.
Summary of Features
Minimum duty cycle: 5% or 10%
I out current to drive e.g. optocoplers: 1mA or 5mA
PWM output frequency: 1kHz
Dimmer/resistor bias current: 120µA
Dim-to-off: disabled/enabled
Benefits
Wide input V cc range: 11-25V, extended range down to 6V
Variable input frequency PWM mode with fixed 1kHz output frequency
Replaces many external components with single chip reducing BOM and PCB space
Minimum variation from device to device
Potential Applications
LED drivers needing 0-10V dimming circuits
Luminaires
Troffers
Downlights
Sconces
Undercabinet
Office lighting
Signage applications
Applications
LED strips and signage
