NXP Semiconductors ASLx416 LED Buck Driver ICs

NXP Semiconductors ASLx416 LED Buck Driver ICs deliver constant average current to LEDs independent of the input voltage. The ASL2416SHN buck driver supports up to two output channels, while the ASL3416SHN supports up to three output channels. These LED driver ICs provide a cost-effective solution targeting automotive exterior lighting applications. NXP ASLx416 LED Buck Driver ICs feature a hysteretic buck DC-to-DC topology. These LED buck drivers allow maximum flexibility on output voltages for each channel with input voltages from 10V to 80V. The ASLx416SHN buck drivers give a flexible system design that can be used to drive two or three LED strings with the same architecture. These buck drivers provide an SPI interface for extensive control and diagnostic communication with an external microcontroller.
