Evaluation Boards – DC/DC & AC/DC (Off-Line) SMPS

The LM5018EVAL/NOPB evaluation board is a DC/DC and AC/DC (off-line) switching mode power supply that can be used to evaluate the performance of the LM5078 buck and boost converter. It provides a feature-rich platform for testing and verifying the design of a variety of DC/DC and AC/DC (off-line) SMPS applications.

This power supply evaluation board has maximum input line voltage of 90 V, and the minimum input line voltage of 15 V. Additionally, it includes two output channels that support both buck and boost operations. The board also features adjustable switching frequency, integrated soft-start, control logic, high/low-side MOSFET protection, an adjustable feedback control loop, EMI filters, over-current protection, and short-circuit protection.

The board also features two parameter adjustments: the output voltage of buck and boost circuitry, and the frequency of the switching converter. Additionally, it features a wide range of compensation options, such as an adjustable frequency compensation with a voltage divider to achieve an optimal at a certain frequency. Furthermore, the board features an adjustable load line for dynamic load regulation, and a load current limit.

In addition to the features mentioned above, the LM5018EVAL/NOPB evaluation board also includes an external control pin, which can be used to enable or disable all the outputs. This enables the user to disable the board when it is not in use, and a soft-start feature reduces turn-on/off transients. Additionally, the board features a low-noise operation, resulting in minimal audio noise in audio power applications.

To further illustrate the working principle of this board, it can be used to illustrate a non-isolated buck/boost converter application. In this application, the LM5018 evaluation board is used to control the input and output currents to regulate the output voltage. The board is configured to connect the input and output pins to the power source and load, respectively. The buck and boost stages of the LM5018EVAL/NOPB evaluation board will then be used to adjust the output voltage by varying the duty cycle of the switching signal. The regulated output voltage is then transmitted to the load through the output pin at the required voltage level.

The LM5018EVAL/NOPB evaluation board also allows the user to perform a load transient test. This test evaluates the performance of the board by simulating a changing load in order to measure the board’s response. This board provides the user with a convenient platform to test a variety of DC/DC and AC/DC (off-line) SMPS applications.

In conclusion, the LM5018EVAL/NOPB evaluation board is an excellent platform for testing and verifying the design of a variety of DC/DC and AC/DC (off-line) SMPS applications. It provides the user with a feature-rich platform for testing and verifying the design of a variety of DC/DC and AC/DC (off-line) SMPS applications. Additionally, the board features adjustable load line, soft start, and adjustable performance parameters, as well as many other features.
