Vishay Exterior LED Fog Lighting Solutions

Vishay Exterior LED Fog Lighting Solutions address the automotive front where lighting provides a stable input voltage for the switched-mode current regulator, an essential tool. First, the battery voltage has to be stabilized with a Buck-Boost to provide a stable input voltage to the following multiple Buck converter stages. Depending on LED-string solutions, the total current defines the power level of various buck stages. The main buck-boost has to have the full power level for the complete lighting control unit. The efficiency of buck-converters depends on synchronous or non-synchronous topology. The light engine is also a feedback loop for LED-string current control and is quite essential.
