core regulators are used to provide the power supply for the CPU core and graphics (GPU) core in computing applications such as Desktop PC, Notebook PC, Server, Industrial PC, etc. Richtek has introduced complete single/multi-phase Vcore power management solutions for INTEL and AMD based platforms. We offer discrete as well as highly integrated PMIC solutions which are fully compliant with the voltage regulation specifications. Richtek’s Vcore solutions feature 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. Vcore products have been extensively verified in customer designs, with easy design, high reliability, high power density, low total BOM cost, fast load transient response, precise current balance under all load conditions, and excellent stability. We also provide smart design tool and GUI which can reduce design effort and shorten design cycle.
|USB Type-C & PD Solutions||
As a member of the USB Implementers Forum (USB-IF), Richtek has been developing innovative USB Type-C and PD compliant products to meet the latest standards for a diverse range of applications, including USB-PD power adapters, mobile chargers, car chargers, Type-C cables with e-Markers and applications with Type-C interface. Our products compliant with the latest USB PD3.0 PPS protocol can also support Direct Charge systems for fast charging.
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.
|Supervisors & Reset ICs||
Richtek provides a wide range of power monitoring, protection and resets ICs to monitor system conditions and ensure normal operations. The monitoring and protection ICs can monitor a supply rail for over/under-voltage conditions to avoid any damage to sensitive devices downstream. The reset ICs can help monitor the supply voltage of microcontrollers and generate a reset signal when the supply drops below a certain limit. These devices integrate different features to ensure system health across all applications.
Richtek provides multi-channel power management ICs (PMICs) with special features developed for the power requirements of various applications or platforms, which can be applied in automotive applications, industrial SoC power, hand-held devices, SSD, TV SoC, PC platforms and general power management.
|Memory Power Solutions||
Richtek offers diverse DDR memory power solutions including linear DDR terminators and PMICs. The linear DDR terminators have both source and sink functionality and provide very tight output voltage regulation. These parts can be used with various types of (LP)DDR memory. The low Vin linear DDR terminators require an external low power bias voltage. Selecting a suitable product for your applications should be based on the DDR type, current rating and features such as output voltage sensing, REFOUT and different power state settings via S3/S5 pins.
Low dropout linear regulators (LDOs) can be used in applications which require to drop a higher input voltage to a lower output voltage at relatively moderate power levels. Richtek has developed a broad portfolio of LDOs which feature high power supply ripple rejection (PSRR) to keep the output voltage free of noise and ripple, low quiescent current (Iq) to extend battery life and different packaging for various power dissipation. The wide input-voltage LDOs operating in wide temperature rating can be applied in industrial applications. The high-performance AEC-Q100 qualified LDOs are ideal for automotive applications.
|LCD & OLED Display Power||
Richtek offers an extensive display power portfolio, including LCD bias and OLED power drivers, ideal for portable or wearable applications. Supporting high responsiveness to deliver the best picture quality, our driver products in unique topologies can optimise power efficiency for various display sizes. Richtek has built on the essentials to offer next-generation applications with higher current loads. We also provide design tools and technical resources to accelerate your design time.
|Gate Drivers & DrMOS||
Richtek’s MOSFET Gate drivers are designed for core voltage supplies in motherboards as well as mobile computing applications that require high efficiency and excellent thermal performance. Combined with Richtek's series of multi-phase Buck PWM controllers, our MOSFET drivers provide a complete core voltage regulator solution for advanced microprocessors. DrMOS integrates a driver and power MOSFETs into a small package to complete power stage switching function. The parasitic parameters are greatly reduced compared to discrete solutions, so the switching loss is also reduced. A significant reduction of switching losses enables superior efficiency at higher switching frequencies. High reliability and low electromagnetic interference, combined with high power density, enable designers to save board space and still deliver superior performance.
|BLDC Motor Drivers||
Richtek offers a wide range of motor driver solutions covering the requirements of brushless DC motors for home appliance, PMSM/BLDC motors, water pumps, cooling fans, etc. Our portfolio includes motor controllers, motor drivers, system integrated power modules. With the complete product portfolio and advanced sensorless sine-wave FOC control algorithm, Richtek aims to provide our customers flexible, easy-implement, and exceptionally reliable motor driver solutions. We also provide firmware and hardware technical support from product development through to launch.
Richtek offers a wide range of battery chargers and wireless power solutions as well as battery gauges and protection devices. Our battery management products and supporting tools accelerate the design of high efficient and high performance battery-powered applications.
Richtek provides comprehensive products for switching power supplies that complete AC-DC conversion, including PFC controllers, flyback PWM controllers used in switching power supplies, secondary side regulators, synchronous rectifier controller and more. Our products with different features meet various application requirements and optimize the performance. Designing with our products simplifies the design process by reducing the number of components and improving system reliability.
