The RT2855BLGQW is a DC DC Switching Regulator from Taiwan Semiconductor which offers a wide range of features and high efficiency performance in a small package size. The RT2855BLGQW is designed to regulate the output voltage of DC-DC converters such as switched-mode power supplies. It is a high-frequency DC-DC power operation with a synchronous PWM control as well as active current-mode operation. It is capable of controlling the output voltage accurately through a precision internal gain, and features low-ripple constant frequency current-mode outputs. This makes the RT2855BLGQW suitable for powering a wide range of electronic components, including but not limited to microprocessors, analog and digital integrated circuits, FPGAs, and embedded systems.

The RT2855BLGQW has a wide input voltage range of 4.5 to 30V and an output voltage range of 0.6 to 10V. It offers several advantages, including an input current limit from 2A to 6A to protect both the power supply and load from damage, and a power-ON reset to ensure the output is initially below the logic threshold. It also comes with a temperature compensation feature for improved output regulation, as well as an enable pin which allows for stand-by mode or shutdown. The product is rated up to 10W output power and an operating ambient temperature range of 0 to 70°C.

The RT2855BLGQW is typically used in applications such as servers, routers, laptops, and mobile devices. It can be used in automotive and inductive charging applications as well. In addition, it is a suitable choice for non-isolated, high power point tracking systems.

The RT2855BLGQW’s working principle is based on its high-frequency, synchronous PWM control, as well as its active current-mode operation. It is capable of controlling the output voltage accurately by using a precision internal gain. Moreover, the device offers a low-ripple constant-frequency current-mode output. The synchronous PWM control ensures that the output voltage is regulated and maintained at a fixed voltage level. It also ensures that the system is protected from over-current and over-voltage conditions. The RT2855BLGQW’s active current-mode operation is responsible for controlling the output current and controlling it to the constant-frequency current-mode. This feature allows for the optimal power output and prevents excess power consumption.

In addition to its excellent features, the RT2855BLGQW has a wide input voltage range, is power efficient, and meets the overheating protection requirements of the standard EN60950-1. This makes it an ideal choice for electronic applications that require increased power supplies. This is evident in the fact that it is found in a wide range of electronic products. From server, routers, and laptops, to automotive and inductive charging applications, this device offers the necessary features and performance to meet the requirements of today’s power supplies.
