LM2771SDEV

LM2771SDEV is an evaluation board designed for DC/DC & AC/DC (Off-Line) SMPS systems. It includes integrated power MOSFET, gate driver, current sense, bootstrap diodes, and other components needed for a fully functional and optimized design. The board has built-in reference designs for quick device evaluation. It also features configurable feedback and current limit settings, allowing users to adjust output current level, voltages, and power stages as needed to optimize performance of their application. The board supports wide input voltage range, from 4V to 60V, which enables it to be used in a variety of applications, such as automotive, medical, and industrial equipment.

LM2771SDEV works in two main sections. The first is the power stage section which converts input voltage to desired output voltage and current. It consists of the MOSFETs, driver, transformer, diode, and other components. The second section is the control stage, which monitors and regulates the output voltage and current. It includes an optocoupler, reference, and current sense circuitry. When using the reference design, users can take advantage of the adjustable current limit and cycle-skip function to avoid excessive dissipation.

The LM2771SDEV board features wide input voltage range and wide output current range which make it ideal for automotive, medical, and industrial applications. It also has built-in diagnostic LEDs that provide alert conditions so users can easily identify potential faults. Furthermore, it is extremely rugged and reliable, making it suitable for harsh environments. With its advanced design and various features, the LM2771SDEV board is an excellent choice for DC/DC & AC/DC (Off-Line) SMPS systems.

In conclusion, the LM2771SDEV board can be used in DC/DC & AC/DC (Off-Line) SMPS systems. It is equipped with a wide input voltage range, integrated power MOSFET, gate driver, reference designs, adjustable current limit and cycle-skip functions, and built-in diagnostic LEDs. With its advanced and reliable design, the board is suitable for various applications, such as automotive, medical, and industrial equipment.
