The evaluation boards provide a wide input voltage ranges and enable users to select output current, output voltage, and operating frequency range.

TPS613221AEVM-019 evaluation boards come with components like inductors, capacitors and resistors to make a complete power solution for a variety of applications, including DC/DC and AC/DC power conversion, LED lighting, power supply, telecom, automotive and industrial. The boards include an onboard 3.3V voltmeter/controller for accurate measurements of applied voltages, enabling users to monitor and troubleshoot their designs.

The evaluation boards are designed with adjustable features that can be adjusted to meet the voltage and current requirements of different applications. The boards feature a wide input voltage range of 4.75V to 25V and a wide output voltage range of 1.2V to 24VThe adjustable features include input voltage, output current, output voltage, switching frequency, and soft start capabilities.

The working principle of the TPS613221AEVM-019 evaluation board is based on the controlling of the oscillation frequency of an inductor-capacitor (LC) resonant tank circuit. This resonant tank circuit is connected to an associated control IC (integrated circuit) that is used to convert the direct current (DC) input power into an alternating current (AC) output power. The AC power is then rectified and regulated to provide the adjustable output voltage. The frequency of the oscillation is determined by the inductor and capacitor values in the tank circuit. By adjusting the inductor and capacitor values, the exact frequency of the oscillation can be obtained to achieve the desired output voltage and current.

In conclusion, the TPS613221AEVM-019 evaluation boards are versatile power supply modules that are designed for testing and evaluating the power stages of flyback, buck, and boost DC/DC converters. The boards feature adjustable features that can be adjusted to meet the voltage and current requirements of different applications and are designed with components like inductors, capacitors, and resistors. The working principle of the boards is based on the controlling of the oscillation frequency of an inductor-capacitor (LC) resonant tank circuit.
