The NCP3101BUCK2GEVB is an evaluation board belonging to the Evaluation Boards - DC/DC & AC/DC (Off-Line) SMPS category. It is a two-stage, synchronous, step-down LED driver designed to meet the highest efficiency requirements. Using the NCP3101A device, it achieves efficiency up to 95% and reduces external components keeping both cost and total solution size to a minimum. This evaluation board features an adjustable output current of up to 1.2A and is optimized for the maximum efficiency. Its wide input voltage range of 4.5V to 28V DC makes it ideal for use in single-stage converter applications such as those found in industrial, telecom and automotive applications.
It provides a differential remote sensing of the output voltage that improves regulation accuracy when operating in a noisy environment. The board is capable of accepting current mode input, which improves the fluctuations in LED current to a minimum. The user interface implemented on its graphical display provides real-time, control, adjustment and diagnostic capability during the design. It also allows users to test alternative design solutions and determine optimal system settings for specific applications. Its combination of features provides a flexible platform for lamp post-top lighting or AC/DC LED driver applications.
The NCP3101BUCK2GEVB evaluation board features the NCP3101A, a synchronous step-down LED driver that can deliver up to 1.2A at an input voltage range of 4.5V-28V DC. This integrated converter is based on a buck topology that reduces component count while providing high efficiency. It utilizes a unique ZCS/ZVS topology that reduces the external component count while keeping ripples in the output voltage to a minimum. The integrated Soft-Start function that can be programmed to start up at different time intervals, helps smooth inrush current and current peaks.
Its synchronous rectification scheme provides high efficiency and excellent performance at light load conditions. Additionally, the NCP3101A offers a wide range of protection features such as output overvoltage, output short-circuit protection, cycle-by-cycle current limiting, and thermal shutdown. The evaluation board also includes a graphical user interface application kit that enables users to remotely control, adjust and monitor the NCP3101A via their PC.
The working principle of the NCP3101BUCK2GEVB is a two-stage synchronous buck converter topology. The first stage features an internal NPN power transistor that switches at a frequency of 100KHz, with the output voltage regulated by an adjustable voltage controller. The second stage is a high-side N-MOSFET synchronous rectifier which synchronizes with the first stage. This synchronous rectification enables the board to provide high efficiency and excellent performance even at lighter load conditions. The two stages together allow the board to deliver up to 1.2A at 4.5V to 28V DC input, and with an efficiency up to 95%.
The NCP3101BUCK2GEVB evaluation board is ideal for applications in single-stage LED driver designs, such as those found in industrial, telecom and automotive applications. Its wide input voltage range and high power conversion efficiency makes it an ideal choice for applications that require greater efficiency and a small form factor. With its graphical user interface and wide range of protection features, it provides an ideal platform for lamp post-top lighting or AC/DC LED driver applications.
