Taiwan Semiconductor TS19501CB10H Automotive LED Driver is a highly integrated, dimmable LED controller with spread spectrum frequency modulation, ideal for vehicle headlights, daytime running lights, and fog lights. The driver is available now from Mouser.


The device is a single-channel LED driver with low-side-current sense and a wide -40C to +125C operating temperature range. This LED controller supports typical topologies such as Boost, Buck-Boost, and SEPIC, and operates in DCM, BCM, and CCM modes. The jitter function offers an effective spread spectrum to reduce EMI.


Output current regulation of the device is based on average current mode control supervised by a control loop. The fault flag is connected to a pull-up resistor from VDC for highlighting the information of fault and fault status flag is latched by the timer when output is low.


The LED Driver is provided in an MSOP-10EP package and is AEC-Q100 qualified for automotive applications.
