This module is rated for input$\backslash$output voltages up to 12V and can deliver a maximum output current of 10A.

The TPS63020EVM-487 evaluation board is based on the TPS63020 high-speed synchronous converter. The device features extremely low quiescent current (ISCQ) of typically 50uA and 1.2MHz switching frequency. The output voltage is set using external resistive divider and can be adjusted from 0.6V to 1.2V. The TPS63020 provides an optimal separation of the control loop from the power stage, ensuring fast response to load transient and better output regulation.

The TPS63020EVM-487 evaluation board is designed to be used with a common DC power source, such as a battery. It integrates over-temperature protection circuitry and includes all necessary protection circuits to ensure safety and reliability of the user’s design. The board also features an external power switch for toggling the input power to the evaluation circuit. The evaluation board is designed with an input from the internal battery and can operate in either step-down or step-up mode and with either internally regulated or unregulated input.

The TPS63020EVM-487 evaluation board works by using a DC-DC converter to step down the input voltage to match the desired output voltage. The device utilizes pulse width modulation (PWM) to control the output voltage. The PWM controller circuitry is integrated into the TPS63020 device. It regulates the instantaneous output voltage by constantly monitoring the feedback voltage from the output, and then adjusts the PWM duty cycle accordingly.

In addition to the PWM controller, the TPS63020EVM-487 also features a precise analog current limiter. This limiter ensures that the output current of the converter is never greater than a predetermined level, providing protection to the load and the converter. The evaluation board also features an on-board metering terminal for easy monitoring of power supply parameters.
