The NCP1250B40WGEVB evaluation board is an offline, DC/DC and AC/DC SMPS (Switch Mode Power Supply) that can provide regulated output with high power savings. It is designed to meet the needs of applications such as lab bench supplies, personal computing, television displays, and other applications requiring portable power conversion.

The NCP1250B40WGEVB evaluation board is based on the Zero Voltage Switching (ZVS) topology, a widely used topology for switched mode power supplies. This topology provides high efficiency and cost-effectiveness and is an ideal choice for applications requiring a high power rating. The NCP1250B40WGEVB also features low ripple and built-in protection functions for improved design flexibility.

The evaluation board is powered by a synchronous Buck converter based on the NCP1250 device. The Buck converter operates in current-mode control, allowing the output voltage to be regulated by varying the switching frequency. This allows the user to select the desired output voltage without changing the components, simplifying the design process.

In terms of protection features, the NCP1250B40WGEVB is designed with temperature protection, short circuit protection, and hiccup mode protection. The board also includes comprehensive protection features such as over-current protection, over-voltage protection, under-voltage protection, and power-down protection, providing reliable operation for a wide range of applications.

The NCP1250B40WGEVB evaluation board is designed as a single-sided PCB with a four-layer topology. The PCB includes a 4V to 24V external input voltage range and an output voltage range of 1.15V to 5.6V. It features adjustable switching frequencies from 280kHz to 600kHz, allowing the user to optimize the efficiency and performance of the design.

The NCP1250B40WGEVB evaluation board is ideal for a wide range of applications such as power supply for inexpensive consumer electronics, automotive electronic systems, LED lighting, and portable communication devices. With its high efficiency and cost-effectiveness, the NCP1250B40WGEVB is a great choice for any application that requires reliable power conversion.
