Richtek offers complete power solutions for motherboard application including VCORE, GFX, Switching VR, Linear VR, Load Switch and Power Switch solutions. With Richtek solution, you can get the easiest design, highest reliability, highest power density and lowest total BOM cost.
For some small form factor design, we also provide highly integrated power management integrated circuit (PMIC), which can further reduce component count, board size and then achieve high power density. To reduce your design effort and shorten design cycle, Richtek also provides smart design tool and Graphical User Interface to easily test and control.
