NCP12510B65GEVB 演示板是一款反激式拓扑开关电源，用于演示由 NCP12510 控制器控制的电源的高效率和低空载输入功耗。演示板的工作输入电压范围为 90 Vac 至 265 Vac，可提供 19 V 的输出电压和高达 3.5 A 的输出电流。控制器 NCP12510B 是高度集成的电流模式 PWM 控制器，具有自动恢复 OCP 保护功能。控制器的开关频率为 65 kHz，额定输出功率。当输出功率降低时，控制器会自动将其开关频率折回最小值 26 kHz，并以跳跃模式启动操作，以实现低空载输入功耗。控制器配备了许多保护功能（OCP、OVP、OTP、OPP），以确保电源的安全运行。此外，NCP12510 控制器的高稳健性和高 ESD 能力有助于电源的安全运行。

The NCP12510B65GEVB demonstration board is a flyback topology switched-mode power supply for demonstration of high efficiency and low no-load input power consumption of the power supply controlled by the NCP12510 controller. Demonstration board works in input voltage range from 90 Vac to 265 Vac and provides the output voltage 19 V up to 3.5 A output current. The controller NCP12510B is highly integrated current mode PWM controller with auto-recovery OCP protection. The switching frequency of the controller is 65 kHz for nominal output power. When the output power is decreasing, the controller automatically fold backs its switching frequency to the minimum 26 kHz and initiated the operation in skip mode for low no-load input power consumption. Controller is equipped by a lot of protections (OCP, OVP, OTP, OPP) for ensure the safety operation of the power supply. Moreover, the high robustness and high ESD capability of the NCP12510 controller contributes to the safety operation of the power supply.
