Application Field

The LMK04133EVAL/NOPB board is a cost-effective, single chip evaluation board featuring a complete buck switching regulator solution incorporating a 400V-rated MOSFET and synchronous rectifier. It also features an adjustable soft-start circuit that minimizes inrush current and optimized waveform levels and a power good (PGOOD) signal. This makes it an ideal choice for a wide variety of applications including motor drives, ac-dc converter design, cordless charging, and other power applications.

Working Principle

At its core, the LMK04133EVAL/NOPB works by supplying a regulated electrical current to the load circuit. This regulated current is derived from the voltage sources, such as a battery or wall outlet, through the switching regulator. The switching regulator is an integrated circuit that features the two main components of a switching regulator, the MOSFET transistor and the synchronous rectifier. The MOSFET transistor allows for easy switching on and off of the circuit, while the synchronous rectifier ensures that the load circuit receives the correct voltage by rectifying the incoming voltage.

The LMK04133EVAL/NOPB board offers adjustable parameters, such as output voltage, input voltage, frequency settings, soft start, and under voltage lockout settings. This allows for more flexibility in the design of the project and a better understanding of the behavior of the switching regulator. Additionally, this board offers features such as current monitoring for inrush control and protection against overvoltage, under voltage, over temperature and over current conditions.

Overall, the LMK04133EVAL/NOPB board is an ideal choice for a variety of design and research projects. It provides all of the necessary components and features to ensure that the circuit is stable and accurately operable. The adjustable settings, current monitoring, and integrated protection features make this board a great choice for engineers looking to experiment with different designs and understand the behavior of the regulator better.
