Evaluation Boards - DC/DC & AC/DC (Off-Line) SMPS are used to provide a regulated output voltage from a variety of power sources, including battery, AC line, and digital logic lines. DCM4623ED2K31E0M70 (DCM) is a high performance evaluation board that is designed to meet this power needs. DCM is ideal for applications such as microprocessor core power, mobile phones, laptop/notebook PCs, desktop PCs, server applications, embedded systems, automotive and domestic appliances.

DCM is a Multi Topology Current Mode Resonant Controller IC. It consists of a high performance current-mode resonant controller IC with an integrated gate driver, high voltage MOSFET, power sense comparators and a safety shutdown circuit. The integrated gate driver is capable of driving the MOSFETs at peak currents of up to 75A. The power sense comparators provide an easy way to monitor the input and output voltage levels. It also features built-in thermal and current limit protection.

DCM4623ED2K31E0M70 is made for operating from wide range of input voltages (12V~500V) and provides the necessary protection against accidental reverse polarity, inrush current limiting and output overvoltage. It also provides programmable pulse width modulation frequency for no-load operation and adjustable soft start time to reduce inrush current.

The key features of the DCM4623ED2K31E0M70 are: adjustable soft start and turn-on times; adjustable output current limit and output voltage; selectable current mode control and PWM modulator; selectable peak current limit with hysteresis; programmable overvoltage protection and undervoltage lockout; adjustable switching frequency up to 500kHz; and much more. It also provides various safety features such as output undervoltage protection, surge protection, over-temperature protection and short-circuit protection.

DCM works on the principle of resonant topology, where the output voltage is regulated using pulse-width modulation (PWM) control. When the input voltage is greater than the average output voltage, the duty cycle of the PWM signal is increased, thus increasing the amount of power delivered to the load. As the input voltage drops, the duty cycle is decreased, and the output voltage is regulated accordingly. This helps to maintain the output voltage within a defined range, thus providing a regulated output power.

In conclusion, the DCM4623ED2K31E0M70 is an excellent evaluation board that is ideal for a wide range of applications. It provides a highly regulated output voltage from a wide variety of sources, and its safety features ensure the safety of the device and its surroundings. Furthermore, its adjustable soft start, adjustable current limit and programmable PWM modulators make it easy to set up and use. With these features, it has become one of the most widely used evaluation boards for DC/DC & AC/DC (Off-Line) SMPS applications.
