The NCP1215AADAPGEVB evaluation board is a fully working SMPS (Switched Mode Power Supply) solution designed to demonstrate the performance and capability of the NCP1215 power management IC (integrated circuit). This evaluation board offers a low cost, easy to configure solution for a variety of off-line AC/DC and DC/DC power supply designs, and is tailored for applications such as adapters, chargers, and even general power supply systems.

The NCP1215AADAPGEVB is an off-line SMPS evaluation board featuring the NCP1215 IC-based PFC flyback topology. The NCP1215 has a wide range of features that make it suitable for high efficiency designs, such as its integrated skip-mode current control, low start-up current, and its high temperature rated parts. The evaluation board also includes a low-noise, high power conversion scheme, a magnetic feedback loop, and an active load regulation.

The NCP1215AADAPGEVB evaluation board employs the NCP1215 IC to perform the following functions:

• It regulates ean input voltage from 85 to 265VAC and provides an isolated output voltage ranging from 8V to 17V with stand by power of up to 500mV.
• It offers high efficiency of up to 98%, depending on the load, operating frequency and AC line voltage.
• It provides over current and thermal shutdown protection.
• It offers a variable range of operating frequencies of 60KHz to 200KHz, making the NCP1215AADAPGEVB evaluation board highly compatible with most power applications.

The NCP1215AADAPGEVB evaluation board also features an integrated push-button voltage adjustment system that lets engineers adjust the output voltage at the press of a button. This allows engineers to quickly configure the board to match any specific application.

The NCP1215AADAPGEVB evaluation board\'s output feature set has been designed for efficient operation under a variety of conditions. It features an integrated power factor correction (PFC) controller to regulate the input power that produces a sinusoidal waveform for non-distorted input voltage and current. This noise-free signal improves the board’s noise immunity, and also reduces the total harmonic distortion of the system. The advanced current-mode architecture of the NCP1215AADAPGEVB evaluation board also provides high-speed transient response.

The NCP1215AADAPGEVB evaluation board also has an adjustable peak voltage and auto duty-cycle control loop. In addition, it allows easy tuning of system parameters by providing two separate analog adjustment terminals, one each for peak voltage and duty cycle. This makes it easier to tune the system and minimize non-linearities.

The integrated design of the NCP1215AADAPGEVB evaluation board includes features such as a synchronous rectifier, a low-dropout linear regulator, and an internal transformer with a wide primary turns ratio. These features reduce the size of the board and make it ideal for applications where board size is critical.

The design of the NCP1215AADAPGEVB evaluation board ensures the highest performance and stability under a wide range of operating conditions. The board is also equipped with a number of features to enhance safety, such as current share, overcurrent protection, and over-temperature protection.

In conclusion, the NCP1215AADAPGEVB evaluation board is a low-cost and easy to configure solution for a wide variety of off-line AC/DC and DC/DC power supply applications. It is the ideal solution for engineers looking for high performance and reliability in a small footprint.
