Taiwan Semiconductor TS19501CB10H LED controller
Taiwan Semiconductor introduces a low-cost and highly integrated dimmable LED controller for automotive lighting
Taiwan Semiconductor introduces a low-cost and highly integrated dimmable LED controller for automotive lighting. Design Engineers benefit from spread spectrum frequency modulation.
TS19501CB10H is a single channel LED driver with low-side-current sense and a device temperature grade 1 (-40 °C to 125 °C). The controller supports typical topologies such as Boost, Buck-Boost, and SEPIC, and operates in DCM, BCM, and CCM mode. The jitter function provides an effective spread spectrum to reduce EMI.
