Automotive

Automotive systems include a wide range of functions and products. These include powertrains, chassis control, body electronics, passive safety systems, exterior lighting, 48 VDC boardnet, start / stop, micro hybrid vehicles, full hybrid vehicles (HEVs), and full electric vehicles (FEVs). All of these depend on types of electronic components manufactured by Vishay, including diodes and rectifiers, MOSFETs, optoelectronic products, resistors, inductors, and capacitors.

For Automotive Front lighting is a stable input voltage for switched mode current regulator an important tool. First the battery voltage has to be stabilized with a Buck Boost to provide to next multiple Buck converter stages a stable input voltage. Depends on led-string solutions the total current defines the power level of various buck stages. The main buck-boost has to have the total power level for complete lighting control unit. The efficiency of buck-converters depend on synchronous or non-synchronous topology. For the light engine is also a feedback loop for led-string current control quite important.
