The NCP1340GEVB, part of ON Semiconductor’s Evaluation Boards - DC/DC & AC/DC (Off-Line) SMPS family of products, is a compact, low-cost, low-profile demonstrator board for evaluating the NCP1340 synchronous step-down controller in a variety of application and working environments.The NCP1340GEVB is designed to operate with a wide input-voltage range of up to 15V, allowing it to be used in various applications. This includes basic household appliances, consumer electronics, automotive or industrial solutions, and so on. This board also provides high-efficiency performance with up to 95% efficiency across its operating regions for higher power-supplies.The NCP1340GEVB is based on the NCP1340 controller which is designed to operate as a synchronous stepdown (buck) controller for a power supply voltage of 12V. The NCP1340 can deliver up to 2A of continuous load current and is suitable for regulating the output voltage up to 3A. Additionally, the NCP1340 features Cycle-by-Cycle current, frequency, and temperature limit functions, as well as a fast external divider for precise output.At the other end of the spectrum, the NCP1340GEVB is designed to operate on a wide variety of input sources, allowing it to be used for a variety of applications such as noise-sensitive systems, battery-powered systems, and other applications with strict power management requirements. The board is built around the NCP1340 synchronous step-down controller, which offers significant advantages in space and cost efficiency for the device while also delivering excellent efficiency and power-conversion rate.In terms of working principle, the NCP1340GEVB uses a synchronous step-down switching topology to provide a regulated output voltage from a varying input voltage. The step-down operation ensures that the output voltage is always lower than the input voltage and is regulated through an external divider circuit, allowing for precise voltage control. The board is also able to provide overvoltage and undervoltage protection, even when an input voltage far higher or lower than the expected range is present.In terms of applications, the NCP1340GEVB can be used in a wide variety of applications, including automotive, industrial, consumer electronics and household appliances. Examples of such applications include small plastic power supply, LED backlighting, linear adapter, DC/DC modules, AC/DC adapter, and thin walled modules.The NCP1340GEVB is an ideal solution for those looking for a compact, low-cost solution for evaluating the NCP1340 synchronous step-down controller in a variety of application and working environments. Its wide input-voltage range and high efficiency performance allows it to provide a cost-effective solution for a wide variety of applications. Its fast external divider circuit and overvoltage and undervoltage protection offers a robust and reliable solution, making it suitable for a wide variety of applications.
