Design of' a MOSFET bypass switch for individual pixel control in a matrix LED headlamp application

A low-cost, high performance solution for single LED control in a matrix LED configuration is presented in this paper. The integrated solutions on the chip market are evaluated and an improved discrete, robust LED bypass circuit is designed und simulated. A complex prototype PCB with the proposed LED bypass circuit has been designed and thoroughly investigated. The performance of the proposed LED bypass solution has been evaluated in terms of speed, resolution and power losses.
