The LM2694EVAL is an Evaluation Board designed to evaluate the LM2694 flyback converter from Texas Instruments. It is designed to take in an AC/DC off-line input voltage of up to 20V and provide a regulated output voltage up to 12V. This Evaluation Board is an excellent choice for a variety of applications, such as LED lighting, battery charging, as well as portable medical devices.The LM2694EVAL application can be categorized as Evaluation Boards- DC/DC & AC/DC (Off-Line) SMPS, as the board allows users to evaluate the LM2694 flyback converter. This Application Board offers an easy way to evaluate the performance of this power regulator.The LM2694 is a synchronous buck-boost DC-DC converter with an operating frequency of up to 1.5 MHz. It has an internal high-side and low-side MOSFET with an adjustable switching frequency that can be adjusted from 200kHz to 1.5MHz. The operating range of the LM2694EVAL is from 4.5V to 20V. For the Input voltage range, it is 0.7V to 20V and for the output voltage range, it can be configured from 0.7V to 12V.The LM2694EVAL comes with a design suite and various evaluation parameters that can be used to evaluate the LM2694 converter. The evaluation board has an adjustable secondary side current limit feature with a maximum adjustable output current of 3A. Additionally, the evaluation board features an adjustable switching frequency of up to 1.5 MHz. The board also features an on-board temperature-sensing NTC that regulates the output voltage and provides protection against over-temperature conditions.The evaluation board also provides comprehensive evaluation of the LM2694 converter\'s performance using an external oscilloscope. The user can analyze the ripple, EMI, voltage and current regulation, efficiency, and transient response, among other parameters.The LM2694EVAL permits the user to evaluate the flyback power regulator in multiple configurations. This board supports all the voltage ranges, with the possibility of setting limits for the start -up voltage, the minimum operating voltage, the maximum operating voltage and the minimum output voltage. It can be used in either step-down or step-up modes.The LM2694EVAL works on the principle of using synchronous buck-boost DC/DC conversion, where a switching element (usually a MOSFET) is used to convert the input voltage to the desired output. When the MOSFET is on, the input voltage is transferred to the output load and when the MOSFET is off, the output load is disconnected from the circuit, thus providing electrical isolation. The switching device can be operated at a frequency ranging from 200kHz to 1.5 MHz, allowing the user to optimize the circuit\'s efficiency.In conclusion, the LM2694EVAL Evaluation Board provides a powerful tool for both development and evaluation of the LM2694 power converter. It comes with a design suite and numerous electronic components available for easy inspection and evaluation. Additionally, this Evaluation Board also permits the user to adjust the operating parameters, allowing for a wide range of applications. The LM2694EVAL Evaluation Board is an ideal choice for a variety of DC/DC and AC/DC (off-line) SMPS applications.
