The CDM10V reduces 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 0-10 V 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.
Volume production of the Infineon CDM10V starts in April 2016 and engineering samples, a demoboard and a configuration board are all available now.
