Automotive System Power Supplies ICs

Along with the electronic devices of the vehicle is high performance for example EPS, it becomes necessary for power supply ICs to correspond to large currents outputs, multiple outputs, and functional safety. Toshiba has various of power management ICs with a DC-DC converter and functional safety and provides automotive solutions with high reliability to satisfy the customers demand specification.
