The TPS65261RHBT is a synchronous step-down DC-DC converter belonging to the Power Management IC (PMIC) family of voltage regulators and DC-DC switching regulators. It features two regulated outputs, one of which is adjustable from 0.6V to 1.8V and the other from 1.25V to 5V. Furthermore, the TPS65261RHBT employs a sophisticated control mode that allows for ultrafast transient response and high-efficiency operation for the entire supply voltage range from 2.9V to 5.5V.

The integrated enable pin makes power sequencing simple, allowing fault conditions to be quickly identified. Additionally, the TPS65261RHBT features advanced protection mechanisms that protect the device and the power supply from short circuit, over-temperature, load dump, ESD and overvoltage conditions.

The TPS65261RHBT has been designed to provide a robust, efficient, and reliable solution to power management challenges in a wide range of applications. The device support a wide input range of 2.9V to 5.5V, and its wide output range of 0.6V to 5V allows it to be used in a variety of applications such as automotive, computing, audio/video, and industrial. The device is capable of providing up to 2A of continuous output current, and its low on-resistance of 6mΩ allows for efficient operation across the entire temperature range.

The working principle of the TPS65261RHBT is based on the use of two building blocks – a synchronous rectifier and a voltage feedback loop. The voltage feedback loop is configured such that the desired output voltage is maintained by comparing the output voltage to the reference voltage, and adjusting the duty cycle of the FETs accordingly. The synchronous rectifier is configured to alternately turn on and off the two FETs, thereby regulating the current flow and maintaining the desired output voltage. The two FETs, when used together, improve the efficiency of the device and ensure optimal performance.

The TPS65261RHBT is a highly integrated device that provides a high level of functionality in a small-footprint package. The device is designed to improve system performance and power conversion efficiency, while reducing the overall system cost and size. Additionally, the device is designed to meets the stringent safety requirements of major safety standards such European Union’s RoHS and China’s CPCA.

In conclusion, the TPS65261RHBT is an impressive DC-DC converter solution and is an ideal choice for many applications. Its impressive feature set and versatility makes it a solution that you can count on to meet power management challenges, while its robust safety features provide peace of mind in safety-critical applications.
