Краткое описание:
AEC-Q100 Synchronous Buck-Boost/Boost/SEPIC LED Driver
Дополнительная информация
The IS32LT3959/A is a versatile multi-topology DC-to-DC controller designed to drive high-power LEDs. It can be configured in buck-boost, boost, or SEPIC topologies, making it suitable for automotive and industrial lighting applications where the input voltage may be higher or lower than the LED string voltage. It features an integrated PWM generator for independent brightness control, spread spectrum for EMI reduction, and high efficiency through synchronous rectification. The device includes robust fault protection mechanisms and is AEC-Q100 qualified for automotive reliability.
