The TPS65580EVM-575 is part of a family of Texas Instruments (TI) evaluation boards that belong to the category “Evaluation Boards - DC/DC & AC/DC (Off-Line) SMPS”. This evaluation board provides a showcase for TI’s TPS65580 buck-boost converter, which is capable of delivering up to 15W of power. It is primarily intended as an evaluation platform for the power solution in the “Thin Film on Plastic” (TFP) package.

The TPS65580EVM-575 is ideal for applications that require a stable and efficient DC-DC conversion to provide clean and reliable power. It can be used for a variety of purposes, such as digital home appliances, consumer electronics, automotive applications, and industrial equipment.

The TPS65580EVM-575 is a complete evaluation platform with on-board test points, voltmeters, and current meters that make it easy to assess and analyze the performance of the TPS65580 buck-boost converter. It is designed with a minimum number of external components, and includes TI’s isolated gate driver and power board with an external Schottky diode for simplified paralleling of multiple devices.

The TPS65580EVM-575 is well-suited for applications where cost-effective, reliable, and stable conversion of DC energy are required. It integrates a power solution optimized for switching frequencies from 200 kHz to 600 kHz, with best-in-class efficiency (up to 96%). It also features internal protection mechanisms for over voltage, over current, and under voltage.

The TPS65580EVM-575 is designed around the TPS65580, which is a synchronous buck-boost converter capable of operating from input voltage sources ranging from 2.5V up to 60V. This evaluation board has been designed to suit any application that requires voltage regulation or conversion within its input voltage range for power sources ranging from 5V to 15V. It also features an adjustable output voltage setting, allowing users to customize their voltage points.

The working principle of the TPS65580EVM-575 is based on its synchronous buck-boost converter, which is designed to step up or step down the input voltage depending on the output voltage load range. The internal MOSFETs are operated in a synchronous mode with the boost and the buck stages alternately switching to maintain the desired output voltage. The load regulation is ensured by controlling the duty cycle of the two switching stages, as well as by actively pulsing the low side MOSFET during the buck mode to achieve fast transient responses.

The TPS65580EVM-575 is a powerful and efficient evaluation board that provides users with an ideal platform for the testing and development of their applications. It is a reliable and cost-effective power solution that can be used in a wide range of scenarios, such as digital home appliances, consumer electronics, automotive, and industrial equipment.
