The NCP3063SMINVGEVB evaluation board is designed to evaluate the NCP3063 Enhanced Average Current Mode PWM Controller, an integrated off-line SMPS controller with green-mode and valley-mode operation. The NCP3063 offers multiple protection features including overcurrent protection (OCP), undervoltage protection (UVP), and short-circuit protection (SCP). The NCP3063 is suitable for applications such as power converters, battery chargers, and DC-DC converters.

The NCP3063SMINVGEVB evaluation board is designed with a multi-mode input to enable easy testing of different operating modes. The board incorporates an active valley-mode feature that enables power-transitions at lower switch-on frequency and extended operation at light loads. This feature helps improve efficiency at light loads. The board also uses a combination of on-board analog and digital circuits to provide input and output voltage and current supervision and feedback.

The basic function of the NCP3063 SMINVGEVB evaluation board is to provide the circuitry and control necessary to create a DC-DC power supply. The board utilizes a control IC, an input voltage divider, an output voltage divider, a power factor correction (PFC) front end circuit, an N-channel MOSFET, and an important feedback loop system. The evaluation board takes the input voltage and adjusts it to the voltage and current that is needed by the load. The output voltage is monitored by the feedback loop system, which adjusts the PWM duty cycle to maintain the output voltage and current at the set value. The board can be configured to operate in valley-mode, green-mode, or a combination of these two modes.

The NCP3063SMINVGEVB evaluation board is designed for applications such as off-line power supplies, battery chargers, and offline DC-DC buck converters. The evaluation board is designed with overcurrent protection, undervoltage protection, and short-circuit protection, providing reliable results for any application. The board is equipped with a selectable emulated-line input that enables the user to simulate a line power source. The board also features a power-ok indicator that signals when the output voltage is within the specified range. The board provides a complete evaluation solution for the NCP3063 Enhanced Average Current Mode PWM Controller, helping the user to rapidly evaluate the performance of the IC.
