PMIC - Voltage Regulators - DC DC Switching Regulators

The RAA230123GSB#HA0 is a low side/high side switch mode DC/DC voltage regulator, primarily used as a voltage regulator in portable electronic devices. It is a DC/DC voltage regulator commonly used in scaled-down applications and can operate with input voltages ranging from 3.0 to 30 volts, which helps save up to 30 volts when the input voltage is low or maintain the output voltage when the input is high. In addition, the RAA230123GSB#HA0 can achieve a small size, light weight, fast response, excellent temperature and voltage range, high current carrying capacity, fast switching and high efficiency, making it an ideal choice for most voltage regulation applications.

Application Field

The RAA230123GSB#HA0 is a highly integrated single chip DC/DC voltage regulator which is suitable for portable applications such as cellular phones, e-books, PDAs, audio players, camcorders and digital cameras. The device can be used to adjust the output voltage of these portable electronic devices, while providing an efficient and reliable power solution at the same time. The device can also be used in electric cars, inverters, battery chargers and solar powered systems.

Working Principle

The working principle of the RAA230123GSB#HA0 is based on a MOSFET switch mode design which uses pulse-width modulation to regulate the switching rate of the switching transistors. When the output voltage of the device drops due to an increase in the load or an increase in the input voltage, the controller will switch the MOSFET transistors off, allowing the capacitors to be discharged and providing more energy to the load. On the other hand, when the output voltage of the device is too high due to a decrease in the load or a decrease in the input voltage, the controller will switch the MOSFET transistors on, allowing the capacitors to be charged and providing less energy to the load.
