RT2859ALGQW Integrated Circuits (ICs)

RT2859ALGQW, belonging to the PMIC voltage regulators DC DC switching regulators category, is the latest PWM, or Pulse width Modulated, regulator component from Richtek, a company specialising in PMIC integrated circuits. This component is packed into a QFN 3.3 x 3.3 leadframe package, and specifically designed for portable devices looking to attain higher efficiency from the power source.

Aside from its compact size, this component is embedded with many features to provide an efficient and reliable power solution, such as the high efficiency switching regulator, to keep the power supply steady even when the load changes. Additionally, the RT2859ALGQW also comes equipped with a regulated voltage that can be adjusted with a power control function via external resistors, as well as offering protection features such as under voltage lockout (UVLO), over temperature protection (OTP), ±3% regulation accuracy and more.

In general, this component is applicable in many different applications and usage scenarios, primarily in portable applications, where it can be used to provide steady and reliable power to a number of devices at the same time. Examples include phones, digital cameras, or laptops and any other small devices powered by internal battery.

The RT2859ALGQW works by converting one DC voltage input into a series of waves with a fixed frequency, known as a pulse-width modulation. This wavelength is then used to control the output voltage of the component. The output voltage is then further adjusted according to the load current, with each output pulse differing in length depending on the current level. This allows the component to provide steady power output regardless of the load.

In conclusion, the RT2859ALGQW is a viable solution for power applications in portable devices, with its compact size and various features allowing for an efficient and stable power source. Its pulse-width modulation capabilities give it the ability to adjust to different load currents, resulting in a steady power output.
