The LM26484SQEV is an evaluation board which is designed to evaluate the performance of the LM2648SQEV integrated high-voltage regulator. It is classified under the category of DC/DC and AC/DC (Off-Line) SMPS.

The LM2648SQEV is a highly integrated, quadruple-channel, synchronous, step-down, current-mode regulation switch (SQEV) which is ideal for point-of-load DC/DC conversion with maximum flexibility and minimum external component count. It can support up to four outputs, with each channel able to regulate both low and high voltage, both current and power.

The integrated high-voltage regulator of the LM26484SQEV offers flexibility and superior performance by providing effective output errors of less than 10 mV and efficiencies of up to 90%. It also provides continuous overload protection as well as primary-side short-circuit and over-voltage protection. Additionally, the board comes with a comprehensive suite of analog and digital functions.

The LM26484SQEV can be used in a wide range of applications such as battery chargers, solar energy conversion systems, LED lighting, industrial applications and automotive applications.

The working principle of the LM26484SQEV evaluation board is based on topologies such as the Constant On-Time (COT) and Discontinuous Conduction Mode (DCM). The COT topology is capable of regulating the output voltage, while the DCM topology is used to regulate the current.

The LM26484SQEV can also be used with external control circuits such as the error amplifier and the soft-start circuit. The error amplifier allows the output voltage to be regulated to a predefined level, while the soft-start circuit helps to reduce the inrush current by ramping up the output slowly over a predefined time period.

The LM26484SQEV is a high-performance, low-cost evaluation board which offers excellent flexibility and performance in the areas of industrial, automotive, solar energy conversion, and LED lighting applications. The integrated high-voltage regulator provides stable output voltage and current, as well as overload and over-voltage protection. With the wide range of external control circuits and topologies available, the LM26484SQEV offers a great solution for users who need a high-performance and efficient evaluation board.
