RT8110BGJ8 is a DC-DC switching regulator, which is equipped with a steady and accurate output voltage and comes with a power indicator. It is an ideal solution for portable instruments, consumer electronics and other battery-powered applications. This article is going to discuss the application field of RT8110BGJ8, as well as its working principle, in the context of DC DC switching controllers.

Application field of RT8110BGJ8

RT8110BGJ8 can be used in multiple application fields. One of the primary applications of RT8110BGJ8 is low voltage linear regulated power supplies. It can be used as a main supply for portable electronic and consumer electronic devices to supply a steady and accurate output voltage, over a range of operating temperatures. It can also be used for other applications such as notebook PC/DVD power/charging, USB charging ports, and smartphone battery charging.

Besides that, it can also be used in automotive applications. As its maximum frequency is up to 2.2MHz, it can be used as a car stereo system, dashboard switching regulator, or similar automotive applications. It is also suitable for flyback/forward converters, isolated buck converters, and other applications with high efficiency requirements.

Working Principle of RT8110BGJ8

RT8110BGJ8 is a voltage regulator based on DC-DC switching regulators. It consists of a power switch and an inductor in series. When the power switch is turned on, the inductor conducts high current, which will rise linearly with time. When the power switch is turned off, the inductor needs to release the stored energy as voltage, and the output voltage will be regulated by the control circuit. The inductor also releases the heat produced by the switch.

RT8110BGJ8 incorporates a gradual soft start and low dropout circuitry, allowing stable circuit operation under the minimum VDD conditions. When the input voltage is out of range or VDD rises, the output voltage will be regulated. Besides, it also features multiple safety protections, including over current protection and over temperature protection. All these features make RT8110BGJ8 a perfect solution for low voltage linear regulated power supplies.

Conclusion

RT8110BGJ8 is a DC-DC switching regulator which can be used in various applications, ranging from portable electronic devices to automotive applications. It incorporates a power switch and an inductor in series and works in a manner that the power switch is turned on, the stored energy will be released as voltage, and the output voltage is regulated by the control circuit. Its multiple safety protections also make it a perfect solution for low voltage linear regulated power supplies.
