LED bias is possible with buck-boost LED drivers whether the input voltage is higher or lower than the LED voltage.
The Global Buck-Boost LED Drivers market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
In order to test the MAX25610B automotive high voltage, high-brightness LED (HB LED) controller from Maxim Integrated, the MAX25610B evaluation kit (EV kit) offers a tried-and-true design.
The EV kit uses a 5V to 18V DC supply voltage and is configured for buck configuration. One string of LEDs can receive up to 3A from the EV kit in its configured state.
The string’s overall voltage ranges from 3V to 6V. For internal sensing, the LEDBK- terminal should get the cathode of the LED string whereas the LEDEXTBK- terminal should receive the anode.

The 1.5A synchronous buck LED drivers with integrated MOSFETs MAX20050 and MAX20052 are demonstrated in the MAX20050 evaluation kit (EV kit).
The DC supply voltage range for the EV kit is 4.5V to 65V, and the switching frequency is fixed at 400kHz. Spread-spectrum mode (SSM) is activated to enhance EMI.
Both analogue and pulse-width modulation (PWM) dimming are demonstrated by the EV kit. The EV kit also shows how to defend against short LED, open LED, and overtemperature faults.
