NCP1406V15GEVB is a switch mode power supply (SMPS) evaluation board with an off-line topology. It provides a compact solution for many low-power application fields. This cost-effective board is intended to evaluate the features and parameters of NCP1406V15GEVB integrated circuit.

The evaluation board is configured as a compact, 65W, 19V/3.4A, off-line linear power supply and can be used in applications such as PC adapters, communications systems, and UL-approved power supplies. It is an ideal platform for evaluation and fast-prototyping of switch mode power supplies.

The NCP1406V15GEVB evaluation board comes with a set of features that make it highly suitable for prototyping applications. It includes a full inrush current protection circuit, a protection circuit for short-term high-voltage transients, and a protection circuit for maintaining the output voltage within specifications. In addition, the board features an adjustable on/off delay, adjustable over-voltage and over-current protection, adjustable input voltage sensing, and adjustable output current sensing.

The main components of the NCP1406V15GEVB evaluation board are the NCP1406V15GEVB integrated circuit, a transformer, an optocoupler, a bridge rectifier, and a power input capacitor. The NCP1406V15GEVB integrated circuit is a high-performance, integrated switch mode power supply controller. It is designed to provide high efficiency and good transient response with low cost. The integrated circuit contains all the necessary components for a basic flyback converter, including a level shifter, a voltage regulator, a power MOSFET, an oscillator, a reset circuit, an over-current circuit, and a frequency modulation circuit.

The core of NCP1406V15GEVB evaluation board is the switch mode power supply\'s working principle. The circuit works on the principle of the transformer-based flyback converter, with a level-shifting voltage regulator. The input voltage is rectified by the bridge rectifier, and the output voltage is regulated by the voltage regulator. The power switch MOSFET handles the on/off controlling of the output voltage from the primary side to the secondary side of the transformer, while the oscillator generates a switching frequency of 65kHz, which is suitable for most power supply designs.

Once given an input voltage of between 6V to 19V and an output voltage level of 19V plus/minus 5%, the NCP1406V15GEVB can provide up to 3.4A output current and can achieve up to 88% efficiency. The evaluation board is also capable of many protection features, such as short-circuit protection, over-voltage protection, under-voltage protection, over-power protection, frequency jitter, and transient protection.

The NCP1406V15GEVB evaluation board is an effective platform for testing applications such as DC/DC converters, AC/DC power supplies, and motor drives. It is designed to handle the needs of all low-power applications, making it a highly cost-effective solution compared to other evaluation boards. The NCP1406V15GEVB evaluation board is a great choice for developers looking for a low-cost, high-performance switch mode power supply solution.
