RT8805GQV Application Field and Working Principle

PMIC - Voltage Regulators - DC DC Switching Controllers.The RT8805GQV is a step-down (buck) DC-DC converter controller integrated to a 5-channel high and low-side MOSFETs driver. It contains a single-stage DC-DC converter controller, a voltage feedback and the output voltage range is adjustable down to 0.8V, ideal for high current applications. This controller is designed for a better solution to reduce number of external components to save the space, power and cost on power supply design.The RT8805GQV supports high efficiency at low operation frequency, allowing to reduce heat generated by the power solution. The low operation frequency could also reduce the required Inrush current and EMI issue.The RT8805GQV is a cost-efficient and space-saving power supply component used in many different fields, from providing power for processor cores, memory and system logic on computers, to powering up various loads for applications in automotive, audio, TV and other consumer electronics.Application FieldsThe RT8805GQV is widely used for highly integrated desktop, notebook and other personal computing application systems. It is also used in various kinds of electronic instruments, including medical monitors, power supply management units, industrial control equipment, automotive infotainment systems, communication base station systems and more.Working PrincipleAt the heart of the RT8805GQV lies its switching circuitry. It is capable of establishing a fixed frequency step-down (buck) voltage conversion, using a pair of NMOS transistors (the high and low side) to alternately connect the input voltage source to the output to form a converter circuit.The RT8805GQV controls its MOSFETs to perform pulse width modulation (PWM), a method used to control the output voltage of the converter circuit. This technique works by switching the MOSFETs ON and OFF very rapidly, while at the same time maintaining a specific duty cycle. The higher the duty cycle or ON time, the higher the output voltage of the converter circuit. The opposite is also true; the lower the duty cycle or ON time, the lower the output voltage of the converter circuit.The RT8805GQV also features overvoltage protection, overcurrent protection, temperature protection, soft start and other features to ensure the reliable operation of the power solution.In addition, the RT8805GQV also takes efficiency into consideration. It is designed to provide high efficiency by reducing the amount of energy lost during voltage conversion and energy distribution, which helps in power savings and better thermal performance.Overall, the RT8805GQV is a very advanced, efficient and cost-effective power supply component for various power supply applications. Its multi-channel MOSFETs configuration enables it to provide higher current and power efficiency, while at the same time taking up a smaller space on the board. In addition, its high level of protection and adjustable output voltage range makes it a reliable, customizable and versatile choice for various power supply design needs.
