The LMR12010YMKDEMO/NOPB evaluation board is part of a series of boards used to evaluate the performance of D/C or A/C off-line switching power supplies. The board has many features that are essential in the judging of the efficacy and efficiency of the supply. It includes switches to control the region of operation, shutdown pins, a full featured power control controller, and an analog feedback loop.

The LMR12010YMKDEMO/NOPB board operates with either a single-phase AC mains voltage or a given DC voltage source. It is designed to be triggered and run from either an external PWM signal or its own on-board controller. Using the external PWM signal allows the operator to control the switching frequency and operation mode. The board also supports Synchronous Rectification (SR) mode, soft-start, and differential primary single ended secondary (DP-SES) operation.

The LMR12010YMKDEMO/NOPB board is used to evaluate the efficiency and power factors of a given device, as well as the ability to operate at certain conditions. In order to perform the evaluation, the board can be configured in different ways. The evaluation board is equipped with a variety of user-controlled switches and jumpers. These switches and jumpers are used to select the various operating modes and to control the current limit and the timing parameters.

The board contains a full-featured analog feedback loop to accurately control the output voltage, current and power. The loop consists of integrating error amplifiers to set the operating point and a bandgap reference circuit to ensure that the output voltage stays within a certain range. A monitor/probing circuit and undervoltage/overvoltage protection circuit are also included. This system accurately monitors the power condition of the supply.

One of the advantages of the LMR12010YMKDEMO/NOPB board is that it supports a wide variety of load types, including resistive, capacitive and inductive components. In addition, the board supports a number of topologies, including Flyback, Forward, Push-pull, Half-brdige and Full-bridge. Depending on the configuration, it can also support the Half-bridge plus Synchronous Rectification (SR), and SR plus output current sensing.

Another important feature of the board that must be taken into account is its interface with secondary controllers. Many of these controllers are based on a dedicated I2C standard or other mixed-signal connectivity. The board supports communication protocols such as the I2C bus, SPI bus, SMBus, etc. In addition, it supports isolated feedback connections, allowing the board to be connected to the load side of an isolated output.

The LMR12010YMKDEMO/NOPB evaluation board is a great tool for evaluating the performance of DC or AC off-line switching power supplies. Its features and capabilities make it an ideal platform for a variety of applications. Not only does it provide the user with the ability to control the operation and performance of the system, but it also allows for easy integration of secondary controllers. Thus, the board can be used to accurately evaluate the efficiency and power factors of the device under test.
