Dimming Interface IC Delivers up to 70% Reduction in Component Count

Munich, Germany – April 26, 2016 – Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) today launched the CDM10V. The compact and highly integrated LED lighting 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 component 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 interface 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 optocoupler-ready PWM signal with 0 to 100 percent duty cycle.

The CDM10V can be used across a variety of different commercial and industrial LED lighting applications. This is enabled by one-time configuration of key parameters such as minimum duty cycle (1 to 10 percent), PWM output frequency (200 Hz to 2 kHz), dimmer/resistor bias current (50 μA to 500 μA) and ‘dim-to-off’ functionality. Furthermore, with ‘dim-to-off’ enabled the IC also provides the option of accepting PWM input signals.

Supplied in an ultra-miniature 6-pin SOT package, the CDM10V is ideally suited for use on small PCBs with high component densities. A supply voltage of 11 V to 25 V ensures compatibility with all common LED lighting applications including luminaires, troffers, downlights, sconces, office lighting and signage. The CDM10V joins a comprehensive portfolio of Infineon devices – including driver ICs and MOSFETs designed to simplify and speed the design of LED lighting applications.
