INFINEON TECHNOLOGIESCDM10VD3XTSA1IC: LED dimming interface IC

0-10 V dimming interface IC with dim-to-off The Infineon 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% •Iout 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 Vcc 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
