IntroductionThe ZSR330GTA is a medium-power multiphase voltage regulator which is designed to provide high-speed transient response, tight regulation and noise immunity. It integrates a driver circuit, two buck regulators and two output regulator circuits which is capable of controlling main cores and graphics chips in Advanced Micro Devices (AMD) mobile platforms. This voltage regulator is specially designed to deliver superior efficiency, reliability and power savings to meet the requirements of advanced mobile platforms.FeaturesThe ZSR330GTA is specifically designed for mobile power and performance applications. The device incorporates a wide input voltage range, high output current capability, superior efficiency and low-noise, along with fast transient response and tight regulation. Additionally, it has integrated protection features such as Overcurrent Protection (OCP), Overvoltage Protection (OVP), External MOSFET Limit, Undervoltage Protection (UVP) and Short Circuit Protection (SCP).ApplicationsThe ZSR330GTA voltage regulator is suitable for use in mobile platforms such as compact laptops, netbooks, tablets, smartphones and other handheld devices. It is widely used in main cores and graphics chips to ensure high-quality performance and power efficiency. It is also used in embedded applications such as industrial automation, robotics, automotive, and agriculture machinery.Working PrincipleThe ZSR330GTA works by converting a wide input voltage range into a regulated output voltage. It includes two buck regulators and two output regulator circuits. The two buck regulators convert the input voltage to a lower voltage in two steps, while the two output regulator circuits convert the input voltage to the target output voltage. The two output regulator circuits also provide fine-tuning of the output voltage by allowing adjustments of their current draw. The ZSR330GTA is designed to operate with a wide input voltage range, providing highly efficient performance with low-noise operation. The device provides protection features such as OCP, OVP, External MOSFET Limit, UVP and SCP, which helps in preventing against over-current, over-voltage, under-voltage and short-circuits. Additionally, this voltage regulator has a wide range of output voltage selection from 0V to 30V, allowing for a broad range of application.ConclusionThe ZSR330GTA is a medium-power voltage regulator which is designed to provide high-speed transient response, tight regulation and noise immunity.
