Linear Regulators (LDO)
Richtek portfolio of linear regulator can support low-dropout, high PSRR, multiple output and DDR Vtt applications. With different package preference and input voltage range, you always can find suitable device from our product matrix. More...




Switching Regulators 
Richtek switching voltage regulators provide accurate output voltage regulation with high efficiency for wide range of applications from battery powered mobile applications to high power CORE supply computing applications. To select the correct type of switching regulator, you need to consider the application input and output voltage and load current conditions. More...



Vcore 
Richtek offers complete Vcore power solution for Intel and AMD CPUs, and ever award Intel reference design several times. Richtek’s Vcore solution are featured high accuracy up to ± 0.5%, SVID supporting, CCM/DEM for energy saving, and support no load offset function for system over-clocking. Our modulation technology (G-NAVP) comes from our experience in analog controllers used in PC. More...

Gate Drivers and DrMOS 
The high-power switching supply usually uses a high-power MOSFET or IGBT as a power switch. The gate driver is a power amplifier that accepts pulse signals from a PWM controller and produces a high-current drive input to the gate of high-power MOSFET or IGBT. With the long-term experience in power management designs, Richtek’s gate drivers have been applied in computers, switching power supplies, etc. More...

Power Switch 
Power switches are used to enable or disable a certain supply rail, often used as protection 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. With Richtek&lqquot&s various solutions, you can find the right product to meet USB 2.0 or USB 3.0 requirements.  More...

USB Interface and PD Controllers

In USB Type-C power usage, the power ability and power role are advertised by CC pins. In advance, USB Power Delivery (PD.) negotiation through CC channel can achieve power role swap and higher power, etc. These series products can advertise Type-C and negotiate with port partners by PD protocol. More...
