Buck-Boost LED Drivers
Buck-Boost LED drivers allow LED bias when the input voltage is either above or below the LED voltage. This is ideal in cases such as a single cell Li-Ion battery driving a single LED where the input voltage can vary from 4.2V fully charged down to 2.7V fully depleted while the LED forward voltage can vary from 2V to 4V depending on brightness and temperature. These LED drivers offer the highest efficiency, lowest noise, and the smallest footprints. Other features include integrated Schottky diodes, accurate LED current matching and multiple output capability.
