The TPS54227EVM-686 is an Evaluation board designed to evaluate the Texas Instruments TPS54227EVM. This board is a step-up/step-down DC-DC converter with overvoltage protection, for buck and boost applications. This board is supported by the Texas Instruments Signal Chain Software, which allows customers to quickly set up and configure the device for use. The device inputs are 12V and the outputs are adjustable from 0.9V to VIN.

The TPS54227EVM-686 is a DC-DC SMPS (switch-mode power sup­ply) with a low-side switch configuration. It is a continuous-conduction mode (CCM) flyback switched-mode power supply (SMPS) that includes cycling mode and voltage-mode control. This allows the converter to provide fast, and reliable conversion of voltage for buck or boost and prevents over-voltage surge.

The TPS54227EVM-686 uses a current-mode PWM controller that employs an internal slope generator with an optional master-slave regulator. The master regulator provides accurate and stable output voltage regulation without the need for external tracking components. With the current-mode PWM controller and the optional master-slave regulator, the converter can be employed with a wide range of input voltage sources, from DC to AC, and protective circuits, such as over-voltage and under-voltage protection.

The TPS54227EVM-686 is an ideal solution for applications such as automotive, industrial, and consumer, as well as lighting, telecommunication, and medical applications. The device can also be used in safety-critical applications due to its low operating current and robust performance. Moreover, the EVM operates over an extended temperature range, making it suitable for harsh environmental applications.

In summary, the TPS54227EVM-686 is a high-efficiency, low-power, and low-noise DC-DC SMPS designed for applications that require high-accuracy voltage regulation. The device offers a wide range of input voltage sources and protective circuits, making it ideal for a variety of power supply applications. The current-mode PWM controller with an optional master-slave regulator ensures an accurate and stable output voltage, even at a wide range of operating temperatures. The board’s wide temperature range ensures it is suitable for the most extreme environmental conditions.
