DCM3623EA5N26B4T70 is an Evaluation Board - DC/DC & AC/DC (Off-Line) SMPS. It is one of the most common types of boards used to test and verify the performance of an off-line SMPS. The DCM3623EA5N26B4T70 evaluation board, developed by ON Semiconductor is a complete SMPS solution, which is specifically designed for small off-line applications (typically less than 10 Watts).

The evaluation board consists of two basic parts: the main board and the baseboard. The main board contains the DC/DC switching stages, the output DC-DC regulator, the filter capacitors and components, and the connectors for input and output. The baseboard consists of the AC/DC mains filter switch, the E-MI filter, opto-isolated feedback circuit, and an isolation transformer. The circuit diagram of the main board is shown below.

The main components on the board are the MOSFETs, the air-core inductor, and the bulk capacitors. The MOSFETs are used for the switching stages and the air-core inductor is used to provide good electrical isolation between the input and output. The bulk capacitors are used to store energy during the ON and OFF cycles of the SMPS. All the components in the board work together to provide a smooth, clean, and efficient power output.

The DCM3623EA5N26B4T70 is designed for both synchronous and “brute force” switch mode operation. In the synchronous mode, the device is designed to switch on and off at a rate controlled by the user, typically 400 KHz to 1 MHz, with the ratio between the width of ON and OFF pulses determined by the user. The synchronous mode allows for fine tuning of the SMPS to optimize the output power.), thus providing higher efficiency than the brute force mode.

The brute force mode is useful for applications where lower cost is desired. In the brute force mode, the device is designed to switch on and off with a fixed frequency, typically 400 KHz to 1 MHz. The output power is always determined by the ratio between the switching ON and OFF times. The advantage of the brute force mode is that it is simple to understand and program.

The DCM3623EA5N26B4T70 is a great board to use in applications requiring reliable efficient power design. It can be used for a wide variety of applications such as power supply, LED lighting, industrial control, automotive, and medical. It is cost-effective and easy to use, with a wide range of features including adjustable current limit, frequency range, and low EMI.

The DCM3623EA5N26B4T70 evaluation board is a great way to test and verify the performance of an off-line SMPS. It is easy to program and use, and provides a reliable and efficient power output. With its wide range of features and adjustable options, the DCM3623EA5N26B4T70 is ideal for a variety of applications.
