9, Linear Regulator (LDO)
Linear regulators can convert higher input voltages into lower output voltages for load use in relatively low power applications. Richtek Technology offers a broad portfolio of linear regulators with a variety of different characteristics to meet the needs of different applications.
Richtek linear voltage regulators with high power supply ripple rejection ratio (PSRR) can provide low noise and low ripple, output characteristics, low quiescent current (IQ) consumption of linear voltage regulators to maximize battery life, low dropout linear voltage regulators can try to maintain output voltage stability when the input voltage approaches the output voltage, and linear regulators that can operate over a wide input voltage range and wide temperature range are ideal for industrial applications. AEC-Q100 certified linear regulators are ideal for automotive applications.
10, Integrated Power Management IC
Many conventional applications require multiple power channels or special auxiliary features, and integrated power management ICs can provide targeted solutions that simplify the system design process and reduce total cost of ownership.
11, Monitoring and Reset IC
Richtek provides a large number of ICs with power monitoring, system protection, and reset functions to protect the system and ensure that they are always in normal working condition. When the power supply has abnormal phenomena such as overvoltage, undervoltage, or negative voltage, the monitoring and protection IC can timely disconnect the power supply line or suppress excessive voltage and current to ensure that the load is always in a safe state.
The reset IC can monitor the voltage supply in real time and send a reset signal when it is abnormal, ensuring that the system operates with normal logic.
12, Electronic Switch
Electronic switches can manage the path of analog signals or power supplies, easily achieve signal transmission and circuit protection, and avoid local failures affecting the overall function. They are a powerful tool to simplify system design.
13, Switching Regulator
Switch-mode voltage regulators can achieve voltage conversion with high efficiency over a wide range of input and output voltages, easily meeting the power management requirements of various applications. Users can choose product categories based on the relationship between input and output, and then select specific models according to specific parameter requirements.
14, USB-C and PD Solutions
As a member of the USB Developer Forum (USB-IF), Richtek Technology continues to conduct product research and development that meets the latest USB-C interface and PD protocol standards, and has been widely used in AC-DC power adapters, car chargers, USB-C cables with electronic tags, and other applications with USB interfaces.
15, Vcore Series
Vcore controllers refer to power controllers that power CPU cores and GPU cores in desktop computers, laptops, servers, industrial computers, and other devices. Richtek Technology has provided many single-phase or multi-phase Vcore power solutions for this application, which can meet the needs of Intel and AMD processors respectively.
