Switches

Richtek provides a diverse switch portfolio including power switches, load switches, power muxes and analog switches. Power switches are used to enable or disable a certain supply rail, often used as protection devices for USB ports. These devices have a slew-rate controlled switch-on action to eliminate inrush currents. They also include protection functions such as OVP, OTP and reverse current protection. Whether in portable devices or automotive applications, Richtek’s switch products can meet different application requirements.
