Infineon has started production of an LED lighting interface IC which 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%. Infineon claims its 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 optomcoupler-ready PWM signal with 0 to 100 percent duty cycle.
The CDM10V LED lighting interface can be used across a variety of different commercial and industrial LED applications.
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 portfolio of Infineon devices – including driver ICs and MOSFETs designed to simplify and speed the design of LED lighting applications.
