The compact and highly integrated LED light- ing interface IC allows designers to replace many of the discrete components used in conventional dimming schemes with a single device. Thus, it can reduce the compo- nent count and PCB space needed for dimming circuitry in LED lighting applications by up to 70 percent. Infineon’s CDM10V is the industry’s first single-chip lighting in- terface IC capable of transforming an analog 0-10V input into a PWM or dimming input signal required by a lighting controller IC. The signal is delivered as 5 mA opto- coupler-ready PWM signal with 0 to 100 percent duty cycle.
