NCP3063SMDBSTEVB Evaluating Board – DC/DC & AC/DC (Off-Line) SMPS

NCP3063SMDBSTEVB (also referred to as NCP3063SB) is a specific evaluation board from ON Semiconductor which is used for the evaluation and development of DC/DC and AC/DC (Off-Line) switching mode power supplies (SMPS) using its NCP3063 Switching Regulator Controller. It is a low cost, compact size (24.00 mm × 24.00 mm) evaluation board that offers exceptional overall performance. It comes pre-assembled and pre-tested for the NCP3063 device, so customers are able to quickly and easily evaluate the controller with no hassle. Additionally, as NCP3063SB targets those applications that require high efficiency and low output noise operations, it also clocks peak efficiency up to 91.4%.

Application Field and Working Principle

At the core of the NCP3063SMDBSTEVB evaluation board is the NCP3063 device which is a highly versatile and cost effective controller for DC/DC and AC/DC (Off-Line) SMPS applications. This evaluation board is designed primarily for dc/dc applications such as DC (Direct Current) /DC converters, DC UPS (Uninterruptible Power Supply) systems, switching regulated linear post-regulators, and step-up or step-down switching regulators for a wide variety of applications. It also provides flexibility for designers to create various tailored solutions for multiple AC/DC applications such as power adapters, offline SMPS, front-end Linear Post-Regulators, and switchers for DC output applications.

The NCP3063SMDBSTEVB evaluation board is built with two distinct stages. For the first stage, the NCP3063 device drives an external power MOSFET and transformer in such a way to generate the required output voltage and the current limit is set with the external resistor. This resistor is externally accessible for allowing users to adjust the output current. In the second stage, the output of the power MOSFET is rectified by the diode and filtered by the output capacitor to generate the desired dc output voltage. In general, when operating this board, the output voltage and current are adjusted according to the application requirements with the external adjustment potentiometer and limiting resistor.

In addition, the NCP3063 SMDBSTEVB evaluation board is equipped with many other features that will provide users with convenient operation and complete control. Developers can choose between open-loop and closed-loop regulation mode with the external jumper. This evaluation board also provides users with a very reliable start-up circuit which uses an external resistor to fix the frequency of the internal oscillator. There is also the ability to reduce the power dissipation and EMI (Electromagnetic Interference) spike at start-up and minimum load with the optional external snubber network. Lastly, all the components and board design of this evaluation board are optimized to reduce the total amount of output voltage ripple and improve the system efficiency.

To sum up, the NCP3063SMDBSTEVB evaluation board is a great way to quickly and easily evaluate and develop efficient DC/DC and AC/DC (Off-Line) SMPS solutions. It offers high system efficiency, flexible open-loop/closed-loop regulation modes, and low output voltage ripple. It allows customers to have complete control over their design with its external adjustment potentiometer, resistor, and snubber network. Overall, the NCP3063SMDBSTEVB evaluation board offers an excellent platform for customers to develop their solutions.
