TPS62691EVM-076 is an evaluation module designed to demonstrate the performance of TPS62691xA family of synchronous step-down switching regulators. The TPS62691xA family is designed to meet and exceed the requirements for no-load, low-load and high-load efficiency, and meets all output current requirements in a single package solution. The current regulation is accurate and the temperature coefficient is within the specification limit. With this evaluation module, the performance of the TPS62691xA family can be tested and evaluated.

The TPS62691EVM-076 includes power stage components including input capacitor, output capacitor, bias winding, transformers, resistors, and a micro-controller. The input voltage range is 5V up to 13.2V, and adjustable output voltage from 0.8V up to 3.3V. The TPS62691EVM-076 board offers key design features and excellent performance. It includes the MSP430F2013 microprocessor to control and monitor the state of the regulator, improve transient response and ensure low output voltage ripple. The high-efficiency of the TPS62691EVM-076 is also due to the optimal component selection.

The TPS62691EVM-076 supports multiple operating modes---single operation mode, continuous burst mode, and direct control burst mode to manage light-load operation. The flexible control scheme increases efficiency in a wide range of input and output voltage and output current. Single operation mode provides the output voltage and current with fixed cycles of on-time, off-time, and skip cycles. The ripple frequency is adjustable. Direct control burst mode allows the system to run with very low output ripple and low output current in the skip cycles.

The TPS62691EVM-076 can be used in a variety of applications, such as lighting, networking, gaming, and other demanding applications. It is capable of delivering up to 5A of current and supporting wide input voltage ranges. The module also offers a high efficiency rating of up to 96.5%, making it ideal for applications where every penny counts such as automotive, telecom, and industrial applications. The output voltage ripple is extremely low at 1% maximum, and the output noise is less than 100 µVrms.

With its state-of-the-art features, the TPS62691EVM-076 can provide a smooth and reliable regulation of the output voltage and current. Its wide input voltage range and high efficiency make it useful in a variety of applications. The evaluation module, combined with TPS62691xA family of switching regulators, makes a stable, efficient, and reliable solution for powering circuits and devices.
