Nettet11. apr. 2024 · 98% Efficient, 50W Synchronous Buck-Boost LED Driver. The LT8391 high power buck-boost LED driver in Figure 1 drives 25V of LEDs at 2A from a wide input voltage range. The 60V buck-boost converter operates down to 4V input. When the input voltage is low, input and peak switch currents can be pushed high. NettetSingle lamp type LED headlight functions are simple and are used to switch between high and low beams. In this case, a step-up (boost) converter of about 15 W to 30 W is used. A representative circuit structure is shown below. The output voltage is determined according to the number of LEDs in series and is in the range of about 20 V to 30 V.
