TPS544C25EVM-681 is an innovative evaluation board for DC/DC & AC/DC (Off-Line) SMPS. It consists of Texas Instruments TPS544C25EVM-681 DC/DC & AC/DC (Off-Line) integrated power switches that provide super high power conversion efficiency. This highly integrated switch-mode power supply features an on-board active pre-regulator, which offers excellent line regulation and reduced output voltage ripple across a wide range of load currents and input voltages. Moreover, the power supply also features a low-noise zero-voltage-transition Pulse Width Modulation (PWM) control, allowing for precise power control. The evaluation board is able to directly convert input power to output power up to 600W.

The TPS544C25EVM-681 evaluation board works by accepting a DC input voltage and providing a regulated output voltage. It meets the needs of a wide range of applications, including power over Ethernet (PoE), LED lighting, portable industrial equipment, and motor drives for home and commercial applications. This board simplifies system design by offering a complete SMPS solution which eliminates the need for passive components and external components. In addition, the switch-mode power supply includes pre-defined high-frequency resonant operation which allows for low-noise, very low output voltage ripple, and high-efficiency power conversion.

The TPS544C25EVM-681 evaluation board can provide output voltages in the range of -2.2V to 14V, and supports a range of output currents of up to 18A. It also comes with a 2.3A start up current limit, allowing for burst-mode power delivery in order to reduce output voltage ripple, as well as a built-in error amplifier for over voltage protection. The board is designed to minimize EMI emissions and provide good thermal performance. Moreover, it also comes with an external reset input which allows system designers to configure the output voltage remotely.

The TPS544C25EVM-681 evaluation board is a complete DC/DC & AC/DC (Off-Line) SMPS system, designed to help customers rapidly develop and evaluate prototypes of their next-generation power systems. It enables designers to quickly test and evaluate the performance of their designs before committing to a mass production run. The comprehensive power stage of the board is well suited for applications requiring a high-efficiency, low-noise, low-output voltage ripple design. Moreover, by using the flexible control features of the board, customers can also make fine adjustments and improvements to their power system designs to further increase efficiency and reduce component count.
