LT8391 4V to 60V FourSwitch Synchronous BuckBoost LED Driver Powers a 25V 2A (50W) String of LEDs at Up to 98 Efficiency. Figure 2. (a) The Efficiency of Figure 1 50W LED Driver Has a Peak of 98 and Ranges from 95 to 97 Throughout the Typical 9V to 16V Automotive Input Range.The LT3744 positivetonegative boostbuck (boostmodethenbuck) is also a low input and low output ripple LED driver, but uses a synchronous stepdown converter with negative regulation capability. High efficiency is a major strength of a synchronous switching IC, especially when a high power LED string is driven such as the 3A, 48W LED load synchronous buck-boost led driver
