The TPS2113AEVM-581 is an advanced evaluation and demonstration board, which is designed to support the TPS2113A synchronously rectifying switching regulator. The board is optimized for a variety of applications, such as noise-sensitive applications, system power distribution, and high efficiency DC-DC applications. By providing support for both a synchronous and an asynchronous topology, the board allows designers to quickly and easily evaluate the performance and features of the TPS2113A device.

The circuit board of the TPS2113AEVM-581 comes with an adjustable output voltage regulator, a buck converter, and an adjustable switching current limit. The adjustable switching current limit ensures high efficiency in design by allowing the designer to control the current limit of the buck converter and its resources. Additionally, the board is equipped with two outputs that can be used to provide multiple devices with separate or combined power supply.

The TPS2113AEVM-581 supports a wide input voltage range, from 4.5V to 16V. The board also supports both a single-stage and a multi-stage synchronous switching configuration. The single-stage configuration is suitable for applications such as digital video equipment, DC/DC power supplies, and LED lighting applications. The three-stage synchronous switching works by using two loop converters in parallel, thereby allowing optimal performance over a wider range of input and output voltage.

The main features of the TPS2113AEVM-581 include high efficiency synchronous rectification, low output ripple, wide input voltage range, active current unbalance compensation, programmable soft start, and adjustable switching frequency. The board also comes with an on-board LED indicator, which displays when the device is in the active state. Furthermore, the board comes with a multi-function pushbutton, which can be used to change the device’s operation modes. This feature is especially useful for board testing and evaluation applications.

The working principle of the TPS2113AEVM-581 can be summarized into three basic steps. First, the primary switch is enabled and the current limit is set according to the operating conditions. Then, the rectifier diodes switch on and the output voltage is regulated according to the preset limits. Finally, the output voltage is maintained and the current limit is adjusted for optimal efficiency.

The TPS2113AEVM-581 can be used in a range of different applications. Its adjustable switching current limit, wide voltage range, and excellent efficiency make it an ideal choice for applications in which high efficiency, noise sensitivity, and system power distribution are the key specifications. Common applications include digital video equipment, LED lighting, and DC/DC power supplies.
