LM2661/3/4EVAL

The LM2661/3/4EVAL evaluation boards are designed specifically for the LM2661/3/4 DC/DC and AC/DC (off-line) SMPS controllers. These evaluation boards provide a quick and easy way to evaluate the performance of these controllers with the exact components required for their specific application, making it possible to test the controller with minimal development time and cost.

LM2661/3/4EVAL provides a versatile platform for exploring these converters’ wide range of features and parameters, including over-voltage protection, output over-current protection, and temperature sensing. In addition, this evaluation board offering includes options for dual-output and interleaved topologies.

The LM2661/3/4 evaluations boards use a recognized power stage and thermal solution such as the NCP1451 and NCP1423 to minimize board design complexity and provide an optimized SMPS design. The boards feature: a wide input voltage range, up to 25 volt output voltage, adjustable peak current limit and adjustable output voltage.

The LM2661/3/4EVAL features a comprehensive control interface, including an SPI bus, analog voltage and PWM input that allows the user full control over converter parameters. The evaluation boards also include safety features such as a soft-start circuitry, over-voltage protection, and over-temperature protection. Additionally, the board has an open frame design to facilitate thermal characterization.

The LM2661/3/4EVAL boards are a great tool for quickly evaluating and prototyping a wide range of DC/DC and AC/DC SMPS designs. The boards provide the user with the flexibility to easily adjust the design to meet their specific application requirements. The boards are ideal for designers looking to evaluate these high-performance controllers for design implementation and to ensure compliance with design requirements prior to implementation.
