Texas Instruments’ TPS62221EVM-014 evaluation module is designed to help engineers evaluate the features of the TPS62221 synchronous buck (step-down) converter. The device is used in off-line DC/DC and AC/DC SMPS applications ranging from 2.3V – 16V input voltage and up to 2A of output current.

The TPS62221EVMs reference design allows users to explore the application of the device, as well as test and measure various parameters. Also, it provides a platform for engineers to perfect their own application and verify their design.

The device features a synchronous buck converter with integrated high-side switches, a fixed frequency and current mode controller, and a voltage feedback loop. Additionally, the TPS62221EVM-014 features a third-order low-pass filter, temperature sensing, and open loop mode operation.

The device’s work that involves regulating, switching, and controlling the output voltage from a DC or AC input source, takes place in three steps.

First, the incoming voltage is converted into a regulated DC voltage using a synchronous buck or boost converter. Then, the voltage is switched at a constant rate through a low-pass filter to minimize noise and high-frequency harmonics. Finally, the output voltage is regulated against a control voltage setpoint to ensure desired voltage accuracy.

The TPS62221EVM-014 provides users with the ability to experiment and test devices for DC/DC and AC/DC SMPS applications. The device also helps engineers perform pre-production testing of their own detailed application design. Furthermore, users can adjust settings such as frequency compensation, inductor selection, soft start, loop compensation, power sequencing, etc., as well as measure current, voltage, and temperature.

This reference design helps engineers perform various tasks and obtain data required in the development process. With the TPS62221EVM-014, users can also develop detailed applications such as motor control and lighting sequencing, as well as other applications specific to the customer’s requirements.

The TPS62221EVM-014 is an essential component for engineers designing off-line DC/DC and AC/DC SMPS applications. It provides a platform for users to develop and refine their application designs, as well as measure and test performance. With its easy-to-use design, engineers can develop efficient performance in a wide range of applications.
