ON Semiconductor NCP1399AGDR2G High Performance Resonant Mode Controller

The ON Semiconductor NCP1399AGDR2G is a cutting-edge resonant mode controller designed for high-efficiency, high-density power supply systems. This advanced controller is a perfect solution for driving Half-Bridge resonant converters in a compact and efficient manner. The NCP1399AGDR2G integrates a wealth of features to ensure reliable and optimal performance in applications such as flat-panel televisions, desktop monitors, and server power supplies.

Key to the NCP1399AGDR2G's performance is its ability to operate in both fixed frequency and variable frequency modes. In fixed frequency mode, the device enables designers to set a stable operating frequency, which simplifies the design of the magnetic components and the control loop. The variable frequency mode, on the other hand, allows for Zero Voltage Switching (ZVS) over a wide load range, which significantly improves efficiency by minimizing switching losses.

The NCP1399AGDR2G boasts a high driving capability, with its high-voltage drivers capable of directly driving a power MOSFET. This feature simplifies the circuit design and reduces the bill of materials by eliminating the need for additional driver components. Moreover, the device includes a variety of protection features such as overcurrent protection, overvoltage protection, and brown-out protection, ensuring safe operation under abnormal conditions.

Another notable feature of the NCP1399AGDR2G is its Adjustable Dead Time Control, which provides designers with the flexibility to optimize converter efficiency and EMI performance. The controller also offers a frequency foldback capability, which reduces the switching frequency under light load conditions to maintain high efficiency across the entire load range.

ON Semiconductor's NCP1399AGDR2G is available in a compact SOIC-16 package, making it an ideal choice for space-constrained applications. With its robust feature set and compact form factor, the NCP1399AGDR2G resonant mode controller is a highly efficient solution for modern power supply designs, delivering performance and reliability that designers can trust.
