RT8298AGSP

PMIC - Voltage Regulators - DC DC Switching Regulators

The RT8298AGSP is an integrated DC/DC regulator with rated output current of 5A and an output voltage of 3.5V to 6V. The device provides a highly accurate lowside power MOSFET current sensing and output current protection. The main feature of this device is the built-in dual-channel current sharing PWM controller capable of supplying between 8 to 10A of output current.

Application Field

The RT8298AGSP is a high-efficiency switching power IC, primarily intended for use in power management applications including mobile phones, tablet computers, laptop computers, digital cameras, and audio players. It can be used in notebooks, PDAs and other portable system to provide a stable source of power for the processor and other peripheral devices, as well as for alternative power systems in car audio and digital home appliances. It is ideal for providing low voltage regulation for any application where a compact solution is needed.

Working Principle

The RT8298AGSP uses pulse width modulation (PWM) to regulate output voltage. The IC uses an oscillator to generate clock signals, which control the on-time of the output switch. This type of regulation is known as pulse width modulation, or PWM for short. PWM works by turning the output switch on and off at a high frequency and changing the duty cycle of the switching action. The duty cycle is then adjusted such that the average output voltage is held within a fixed range. The RT8298AGSP also utilizes a built-in, digitally-controlled current/voltage system that allows users to adjust the output current and voltage more precisely.

The RT8298AGSP has an over current protection function that restricts the output current to the predetermined value when an over current situation occurs. The IC also provides an internal thermal shutdown circuit to prevent the device from overheating and damaging the system. In addition, the IC has an over voltage protection mode that prevents the output voltage from going higher than the maximum predetermined value.

The RT8298AGSP is designed to operate in extreme temperature conditions and has low power dissipation, making it suitable for a wide range of operating environments. it is also designed to offer a high level of efficiency and low noise operation, making it an ideal solution for customers looking for a cost-effective and reliable DC/DC solution.
