RENESAS GS61008P automotive 48V/12V Bidirectional dc-dc converter is powered by GaN Systems’ 100V enhancement mode GaN-on-silicon power transistor to achieve a 46% reduction in system size. Solution is aimed at 48V mild hybrid vehicles and electric motorcycles, which require high efficiency 48V/12V dc-dc converters. Device delivers a 46% reduction of the pcb area by leveraging improved switching capabilities – enabling a high-efficiency power converter with a high switching frequency of 500kHz. This allows the use of very small 1.3µH inductors, which leads to a significant decrease in size and weight. The ISL78226 PWM controller eliminates the need for complicated dc-dc converter control software development.
