The TPS64202DBVR is a DC-DC switching controller, specifically designed for battery-powered and USB-powered applications. It integrates a low on-resistance FET driver, uses low-RDS(on) MOSFETs, and supports up to 6V/3A output. The TPS64202DBVR is composed of an input stage with a low noise power delivery network and a high side switch, and a low side switch connected to an output load, allowing the device to support high switching frequencies far above traditional linear voltage regulator applications.

Application Fields

The TPS64202DBVR’s small size and low power consumption make it ideal for a wide range of applications where limited size and high efficiency are desired. It is well-suited for powering 5V and 3.3V microprocessors, RF transceivers, and other DC-DC applications such as portable PDAs, digital cameras, and printer power supplies. It is also suitable for industrial and automotive applications, where it can be used to reduce the board size and increase the efficiency over linear voltage regulators.

Working Principle

The TPS64202DBVR works on the principle of switching type of regulation, in which the switch is used to control the output. The switch can be an FET, BJT or MOSFET, depending on the requirements of the application. The switching regulator works by turning the switch ON and OFF at a controlled rate, so that only a certain amount of energy is transferred from the input to the output. This results in high efficiency, as only the desired amount of energy is transferred to the output.

The device operates in a continuous mode, meaning that the switching frequency is continuously adjusted to keep up with the changes in load current. This allows the device to have a wide range of output current, which is important for battery-powered applications. The device also supports a programmable switching frequency, allowing for better control and efficiency in different applications.

The TPS64202DBVR is equipped with several protections, such as over-temperature protection, ultraviolet (UV) protection, and overvoltage protection, making it a reliable and safe device. It also supports the ability to monitor voltage and current, making it suitable for battery-powered applications.

In conclusion, the TPS64202DBVR is an efficient and reliable DC-DC switching controller designed for applications where size and efficiency are important. It offers a wide range of protections and monitoring features, making it suitable for residential, commercial, industrial and automotive applications.
