NCP1341GEVB

The NCP1341GEVB is a high-performance, high-accuracy, adjustable synchronous buck-boost converter evaluation board offering a complete system solution for the NCP1341GE Intelligent Power Switch (IPS) controller device. It is specifically designed for applications that require a wide input voltage range and high efficiency, such as advanced power management systems, embedded systems, servers, and desktop PCs.

The NCP1341GEVB evaluation board provides a free-running buck-boost DC/DC topology using the NCP1341GE as the main driver. With this setup, the NCP1341GEVB can accept an input voltage ranging from 3V to 32V, and output a regulated voltage between 0.2V and 20V. This feature makes it ideal for applications that require wide input voltage sources, such as those that operate from 12V to 24V automotive batteries and those that use alternate energy sources. It also offers a wide range of switching frequency (between 20kHz and 500kHz) and up to 92% of efficiency.

In terms of features, the NCP1341GEVB offers several protection and control functions which allow for easy integration into an application. It has auto-retry as well as an optional over-voltage protection (OVP) and over-current protection (OCP). In addition to this, it also boasts programmable soft-start capabilities, allowing for a slow power-up or shutdown of the system. It also offers a pre-biased output option, enabling the power solution to be used even if the output voltage is pre-set. The evaluation board also comes with a graphical user interface (GUI) for easy monitoring and control.

In terms of operation, the NCP1341GEVB can be programmed to operate in either a boosted or bucked mode. When in buck mode, the switching frequency of the NCP1341GE is set at 500kHz and the duty cycle is optimised such that the output voltage is fixed at the preset value. In boost mode, the switching frequency is set at a much lower frequency (such as 20kHz) and the duty cycle is optimised such that the device delivers more current. This allows for improved efficiency when running at higher load currents.

The NCP1341GEVB incorporation of the NCP1341GE Intelligent Power Switch (IPS) controller device, makes it an ideal solution for a variety of SMPS applications. It offers a wide input voltage range, high efficiency and wide range of switching frequencies, as well as pre-biased output and graphical user interface. This makes it ideal for applications such as advanced power management systems, embedded systems, servers, and desktop PCs.

Overall, the NCP1341GEVB is a high-performance, high-accuracy, adjustable synchronous buck-boost converter evaluation board offering a complete system solution for a variety of SMPS applications. It can accept an input voltage ranging from 3V to 32V, and output a regulated voltage between 0.2V and 20V, with maximum efficiency of up to 92%. The board also offers several protection and control functions facilitating easy integration of the its output into an application.
