RT9030A-15GB

The RT9030A-15GB is a voltage regulator IC produced by Richtek Technology Corp., a leading supplier of integrated circuits for power management. It is designed to provide a high performance, cost-effective and space-saving solution for controlling current in systems requiring a regulated output voltage.

As a member of the RT9030A family of linear voltage regulators, the RT9030A-15GB is suitable for a variety of applications. With its adjustable voltage output range (2.5V to 15V) and its maximum output current of 15A, the RT9030A-15GB provides a good choice for any system requiring an adjustable output voltage between these values, such as audio amplifiers, telecommunication devices, handheld device, automotive applications, and industrial systems.

The RT9030A-15GB is designed to maintain a stable output voltage from input sources that vary from the nominal input voltage. It features a wide operating temperature range of -40°C to +125°C, and its small SOT-23-6 and standard SOP-8L packages support space-saving solutions. It is also designed to meet the full compliance requirements for lead-free products in the EU.

Working Principle

The RT9030A-15GB is a linear voltage regulator IC with a linear voltage regulation method. It provides stable output voltage through a fixed voltage drop at its output side when the input voltage exceeds the regulator\'s reference voltage. This process of fixed voltage drop at the output side ensures a stable output voltage even if the input voltage fluctuates.

The RT9030A-15GB also has a feedback regulation method which is employed when the load connected to the output is changed. Under this method, the IC regulates the output voltage and adjusts the voltage gain based on the input and output voltages, providing a more accurate output voltage than if the IC were relying solely on the voltage drop method.

In addition to the linear voltage regulation and feedback regulation methods, the RT9030A-15GB provides an HV DSA (High Voltage Dynamic Self Adjustment) technique. This technique is designed to automatically adjust the output voltage depending on the input voltage, preventing over voltage during high current draw applications.
