The NCP1397BDR2G from ON Semiconductor is a state-of-the-art high-performance resonant mode controller designed for use in switch mode power supplies (SMPS) that require high efficiency and reliability. This controller is particularly suitable for applications such as flat-panel televisions, desktop monitors, and other advanced electronics where power efficiency and compact design are critical.

With its high switching frequency capability, the NCP1397BDR2G enables the design of power supplies with reduced size and weight, as it allows for the use of smaller passive components. This resonant controller integrates a variety of features to enhance performance, including adjustable dead time to optimize efficiency, a high-voltage startup circuit that reduces standby power consumption, and a fault management system that ensures robust operation under adverse conditions.

The NCP1397BDR2G offers frequency modulation to mitigate electromagnetic interference (EMI), making it easier for power supply designs to meet regulatory standards. Additionally, its built-in brown-out protection guards the system against conditions of undervoltage, while overcurrent and overvoltage protections safeguard the controller and the power supply from potential damage due to abnormal operating conditions.

Key features of the NCP1397BDR2G include:

• High switching frequency for compact power supply designs
• Adjustable dead time for improved efficiency
• High-voltage startup circuit for reduced standby power
• Frequency modulation for reduced EMI
• Comprehensive protection features (overcurrent, overvoltage, brown-out)

This device is offered in a small and thermally efficient SOIC-16 package, making it an excellent choice for space-constrained applications. The NCP1397BDR2G's combination of features and performance makes it a leading solution for designers looking to create advanced, energy-efficient power supplies without compromising on power or features.

With ON Semiconductor's commitment to quality and performance, the NCP1397BDR2G resonant mode controller is an ideal choice for manufacturers aiming to meet the highest standards of efficiency and reliability in their power supply products.
