RT8073GQW application field and working principle

RT8073GQW is a type of DC-DC switching regulator manufactured by Richtek Technology Corp, a Taiwan semiconductor company which specializes in deep heath analog ICs and power solutions. The RT8073GQW is a highly-integrated DC-DC switching regulator for Embedded Systems and Mobile Devices. It is an ideal solution for delivering efficient and stable power across a wide range of variable input voltages. In addition, the regulator features an integrated output voltage sensor, programmable operating frequency, optional light load efficiency boost mode, frequency jittering and thermal protection to provide a highly versatile, efficient and reliable solution for many applications.

Application Field

The RT8073GQW is designed to support a wide variety of applications, including but not limited to: Embedded systems, Portable PCs, Office Automation, Wearables, Battery-Powered Appliances and Mobile devices. Its wide input voltage range (2.6V - 10.5V) make it suitable for many different types of applications, as it can handle voltage dropouts without breaking down. It is also equipped with a wide output voltage range (0.7V - 5.5V) and a programmable soft-start feature, making it even more versatile.

Working Principle

The RT8073GQW is based on a buck topology, meaning it works by step-downing the input voltage to a lower output voltage. This is achieved through the conversion of electrical energy from a high voltage source to a low voltage level. To accomplish this, the IC utilizes an internal high-side FET and a low-side FET driven by a fixed frequency control circuit. The input voltage is stepped-down to the output voltage by switching these two FETs on and off. In order to minimize power loss, a low ripple output voltage is generated through pulse width modulation.

The device also features several protection functions such as output short circuit protection, over-temperature protection, UVLO (Under Voltage Lock Out) and OVLO (Over Voltage Lock Out). This helps to keep the IC safe from potential damage due to misuse. In addition, the RT8073GQW also provides output voltage sensing, which is used to ensure the output voltage does not exceed its preset limit. This helps to ensure an accurate and stable output voltage.

The RT8073GQW is a highly integrated DC-DC switching regulator that provides efficiency, stability and versatility. Its wide input and output voltage range and additional protective features make it an ideal solution for many different types of applications. From Embedded Systems and Mobile Devices to Portable PCs and Wearables, the RT8073GQW can handle whatever power requirements are thrown at it.
