APEK4447SLJ-01-T-DK is a device that is used to evaluate and measure the performance of DC/DC and AC/DC (off-line) switching power supply systems. It is an application board made especially for this purpose and can be used by engineers to measure and analyze the efficiency and performance of a switching power supply system. The device is made up of an application board and an onboard power supply. It is most commonly used in laboratories, production departments, and industrial facilities.

The application board consists of a buck converters system, high side and low side MOSFET\'s, as well as control components and power MOSFETs. The onboard power is an integrated circuit from the APEK family, which is DC-DC and AC-DC power conversion optimally integrated into this application board, offering a low cost and high performance system. The buck converter system has two operation stages, one in the continuous conduction mode (CCM) and the other in the discontinuous conduction mode (DCM). Each stage can be independently programmed or controlled.

The board offers a wide range of features, allowing it to measure the required parameters of a switching power supply. For instance, the board has a built-in oscilloscope that covers frequencies up to 800MHz to measure the switching frequencies and the transient response. Furthermore, it has well-defined test points for the voltage and current that are acquired by digitalizing the signals from the test points. Additionally, the board has built-in analysis functions, such as a soft start, short circuit protection, and dynamic over-current limiting. This provides an optimal performance for real time operation.

APEK4447SLJ-01-T-DK is an ideal evaluation board for DC/DC and AC/DC (off-line) switching power supplies. It provides users with the power characteristics and performance that are needed to measure and analyze the power supply system. In addition to the analysis functions, it has a wide range of features, including an oscilloscope, test points, soft start, and more. Furthermore, the board is mainly used in laboratories, production departments, and industrial facilities, making it an ideal choice for applications where the highest performance is desired.
