The Texas Instruments TPS63051YFFR is a versatile buck - boost converter. It works with 2.5V - 5.5V inputs, outputs 500mA in boost and 1A in buck mode. With over 90% (boost) and 95% (buck) efficiency, it has a 2.5MHz freq. and power - saving modes. It also has over - temp and under - voltage protection, adjustable soft - start, and a compact 1.6mm x 1.2mm WCSP package.
Texas Instruments TPS63051YFFR's Features
The TPS63051YFFR from Texas Instruments is a powerful buck-boost converter with numerous practical features. It has an input voltage range of 2.5V to 5.5V, enabling it to adapt to a variety of power supply environments. In terms of output capability, it can continuously output a current of 500mA. In the boost mode, the maximum current can reach 500mA, and in the buck mode, it can reach up to 1A, which can meet different load requirements.
This chip is highly efficient, with an efficiency of greater than 90% in the boost mode and greater than 95% in the buck mode, effectively reducing power consumption. It adopts a typical switching frequency of 2.5MHz and has an automatic power saving mode or a forced PWM mode, which can be flexibly switched according to the load conditions. When the load is light, it enters the power saving mode to reduce power consumption and extend the battery life.
In addition, it also has a rich set of protection functions. For example, the over-temperature protection can prevent the chip from being damaged due to overheating, and the under-voltage lockout can avoid misoperation under low input voltage. At the same time, it supports adjustable soft start time, which can reduce the inrush current during startup. This chip is packaged in a small-sized 1.6mm x 1.2mm, 12-pin WCSP package, saving circuit board space and being suitable for application scenarios with strict space requirements.
Texas Instruments TPS63051YFFR's Applications
The TPS63051YFFR from Texas Instruments is a highly integrated power management chip with wide applications in multiple fields. In the consumer electronics field, it is suitable for devices such as cellular and smartphones, tablets, etc. Due to its wide input voltage range (2.5V to 5.5V), high conversion efficiency (boost mode > 90%, buck mode > 95%) and adjustable soft - start time, it can supply power stably for these devices and extend the battery life. In PC and smartphone accessories, it can ensure that the accessories work efficiently under different input voltages and improve the overall performance. At the same time, this chip is also suitable for various battery - powered application scenarios. It can achieve seamless buck - boost conversion when the input voltage is higher or lower than the output voltage, ensuring the stable operation of the device. In the fields of smart grid and smart meters, it can manage power efficiently and meet the requirements of low power consumption and high reliability.
