CDM10VD3XTSA1

CDM10VD3XTSA1 is a flexible 0-10V dimming solution. It is fully integrated 0-10 V dimming interface IC and comes in a SOT23-6 package to cover space requirements on small PCB designs. The device is targeted for various dimming applications in lighting. The IC can be used to transmit analogue voltage based signals from a 0-10 V dimmer or a potentiometer or a PWM input of a lighting controller IC, transformed to a 5mA/1mA current based fixed frequency PWM signal, to directly drive an external optocoupler. To avoid flickering when dimming, the light up and the light down threshold has a minimum implemented hysteresis of 200mV. It replaces many components in a traditional solution and reduces BOM and PCB space significantly. Application includes LED drivers needing 0-10 V dimming circuits, industrial and commercial dimmable applications luminaires, troffers, downlights, sconces, undercabinet, office lighting, signage, Dali.
