LM20333EVAL is an evaluation board for devices of the LM20333 family, designed to drive an isolated DC/DC or AC/DC (off-line) SMPS. It is an easy to use evaluation board that is able to operate as a feedback voltage or current-mode based self-adjusting power supply.

This evaluation board is ideal for the evaluation of the LM20333 buck regulators. It is designed to be compact and reduce component count while allowing users to evaluate different operating modes. With its buck feature, this evaluation board is perfect for developing a powerful, efficient and reliable SMPS.

By default, the LM20333EVAL is configured to drive a 24V/2A AC/DC (off-line) transformer. It is equipped with an adjustable current limiting circuit to protect it from current overloads. For DC/DC regulators, the board contains two high-side MOSFETs and a full bridge rectifier circuit to provide a wide range of voltage and current range.

The LM20333EVAL has various features to allow for flexibility and customizability. It has a selection of feedback modes, allowing the user to choose either voltage or current-based operation. Several configuration pins are available for enabling self-adjusting feedback voltage, pulse-by-pulse current limit and over-voltage protection. By utilizing the open source firmware provided with the board, it is also possible to customize the feedback characteristics to fit the user’s application.

In terms of controlling the different power stages, the LM20333EVAL offers a range of different connectors suitable for delivering digital, analog or PWM signals. Additionally, the board has an LED indicator that gives a visual indication when the output power is present. The board is also equipped with a UART interface that allows convenient communication with the board.

The LM20333EVAL is a versatile and powerful evaluation board that allows users to evaluate the LM20333 family in various different applications and operating modes. It is easy to use and provides a wide range of features. This makes it an excellent choice for power system design and evaluation.
