The Only 0-10V Dimming IC on the Market Today: CDM10V

Infineon’s CDM10V is the industry’s first single-chip lighting interface IC dedicated for lighting applications 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 in the form of a 5 mA optocoupler-ready 0 to 100 percent PWM output. 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 allows the CDM10V to be used across a variety of different commercial and industrial LED lighting applications.

Linear DC-DC IC’s: BCR450/401/402/320

The BCR linear LED drivers are perfectly suited for driving LED currents from 10 mA to 250 mA, making them the ideal choice for low- to mid-power LEDs in general lighting applications.

This represents the lowest-cost solution that requires an ultra-low external part count and PCB space. The light output can be adjusted via an external resistor. PWM dimming is supported either by a microcontroller interface or by means of an external digital transistor. Thanks to its negative thermal coefficient, the LED load will be protected from overheating.

AC-DC Switched Mode Power Management Solution: ICL8105/5101

The ICL8105 is a high-performance configurable single-stage flyback controller with Power Factor Correction (PFC) for constant current output LED drivers. The digital core of the ICL8105, along with its advanced control algorithms, provide multi-operation modes, such as quasiresonant mode, discontinuous conduction mode or active burst mode. Thanks to this functionality and a smooth transition between the operation modes, the controller delivers high efficiency, high power factor and low harmonic distortion through the entire load range.

The ICL5101 integrates a half-bridge controller with a PFC stage in a single package. The high level of integration assures a low number of external components, enabling small form factor designs ideal for compact power supplies in lighting applications, such as LED drivers. All operation parameters of the IC are adjustable via simple resistors, being the ideal choice for an affordable and reliable configuration.
