Recom buck converter powers long LED chains
By means of pulse width modulation (PWM) or analog signal, the drivers can be dimmed to zero. The PWM input can be connected to a microcontroller which manages the communication. The efficiency of the buck controller is up to 96%, the operating temperature range is specified from -40°C to 85°C. For the PCB assembly the module is available with pins or wires. The most powerful version which drives up to 1200mA comes in a metal package; all other versions are provided with plastic casing. All drivers are certified according to EN/UL609020-1. Mean time between failures (MTBF) is with 1.7 million operating hours very high.
The buck converter is designed for use in long LED chains and in multi-chip arrays.
