Richtek offers complete power solutions for notebook application including VCORE, GFX, Switching VR, Linear VR, Load Switch, Power Switch and White LED backlight 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 fit your design in a small PCB. To reduce your design effort and shorten design cycle, Richtek also provides smart design tool and Graphical User Interface to easily test and control.
