The LM25011MY-EVAL/NOPB is an evaluation board designed for use with the LM25011 regulator, one of the most popular integrated off-line switchers. It greatly reduces the costs and complexity of designing a simple, efficient, and compact power supply. The LM25011MY-EVAL/NOPB is an integral part of the industry’s largest selection of evaluation boards and can support almost any type of application.

The LM25011MY-EVAL/NOPB is an efficient, low-cost, off-line switchmode power supply (SMPS) which uses a synchronous rectification approach to reduce the loss in the rectifier. It is designed to provide high-efficiency, compact power at a wide range of loads over a wide input voltage range. The switch is integrated and provides the main control signal needed for the secondary-side of the regulator. The board features many additional components, including integrated capacitors and coils to reduce the physical size of the device, enabling it to meet the needs of many applications.

The LM25011MY-EVAL/NOPB is based on the LM25011 controller, a fixed frequency current mode PWM controller designed for both isolated and non-isolated DC/DC and AC/DC converters. The integrated switch is a current sense type, which is controlled by the LM25011. The controller monitors current level in the switch to ensure that the output current is always kept in the optimal range.By utilizing the excellent performance of the integrated closed loop control, the LM25011MY-EVAL/NOPB can provide high efficiency and good output voltage accuracy over a wide range of input and load conditions.

The LM25011MY-EVAL/NOPB evaluation board can be used to quickly evaluate the LM25011 controller and its features. It can also be used to experimentally explore the SMPS performance. The board has the flexibility to support various output current levels, input voltages and operating frequencies. It consists of two power connections, an input voltage range selector, an output voltage trimmer and an external winding to set the operating frequency. The user can access and adjust all settings on the board. The user also has access to a range of protection features including over-temperature, output over-voltage, output current monitoring, short-circuit, over-voltage and open-circuit protection.

The LM25011MY-EVAL/NOPB is a versatile evaluation board that can be used to create custom solutions for many DC/DC and AC/DC applications. The board is intended for use with prototype designs to ensure proper operation and performance. It can also be used to investigate and develop solutions for specific optimized topologies. With its wide range of performance, the LM25011MY-EVAL/NOPB is ideally suited for applications which require high efficiency, precise control, robust fault detection and excellent performance over a wide input voltage range.
