The NCP1072DIPGEVB Evaluation Board is an evaluation board that keeps most of the components of the NCP1072 DrMOS and utilizes the higher operating frequency, which reduces the total power consumption of an application. This evaluation board is most suitable for evaluating the NCP1072 device, the popular DrMOS in the DC-DC and AC-DC (Off-Line) SMPS (Switched Mode Power Supply) markets. It facilitates fast development for various types of applications, such as notebook adapters, power supplies, and point of load converters.

The applicable range of the NCP1072DIPGEVB is an input voltage range from 9 V to 18 V. It is capable of various output voltages; the maximum output current is 0.5A; and the maximum output power is 6W. The evaluation board comes with some components which are optional, such as the bootstrap diode, timing components, and feedback components). The NCP1072DIPGEVB board was also designed with an easy-to-use graphical user interface (GUI).

The NCP1072DIPGEVB evaluation board is composed of several components. The main component of the evaluation board is the NCP1072 DrMOS device which is a state-of-the-art synchronous rectifier designed for DC-DC and AC-DC (Off-Line) SMPS (Switched Mode Power Supply). The NCP1072 DrMOS is a high-frequency buck regulator using a low-cost MOSFET to boost efficiency. It also provides excellent transient response and high line and load regulation. The board is also equipped with a NCP4302P50 boost rectifier, a IRLZ44N MOSFET, a LM324D comparator, a resistor divider, a ceramic capacitor, a choke coil, a diode rectifier and a fuse.

The working principle of the NCP1072DIPGEVB is based on the operating principles of a DrMOS (Driven MOSFET) integrated circuit, which employs a topology that integrates the power FET and the gate driver within the same package. The general flow of a buck conversion system is as follows: first, the high voltage input is connected to the primary side of the circuit, and the output at a lower voltage is taken from the secondary side. The buck converter then adjusts its output voltage to the desired value by adjusting its switching frequency. To regulate the output voltage, the converter switches the FET at a regulated frequency while varying the width of the output pulses. The DrMOS integrated circuit takes the switching clock from an external source and adjusts the duty cycle of the output transistors, using the feedback components connected to the output terminal.

In conclusion, the NCP1072DIPGEVB evaluation board is suitable for evaluating the NCP1072 DrMOS device in DC-DC or AC-DC (Off-Line) SMPS applications. Its innovative design and layout makes it an ideal tool for developing various types of applications with excellent performance and reliability.
