ON Semiconductor NCP1398CDR2G High Performance Resonant Mode Controller

The NCP1398CDR2G is a high-performance resonant mode controller designed by ON Semiconductor, offering advanced features for efficient and reliable power supply units. This component is particularly suitable for applications that require high efficiency and power density, such as flat-screen TVs, server power supplies, and telecommunication systems.

Equipped with a robust set of protections, the NCP1398CDR2G ensures safe operation under various conditions. It features an Over-Current Protection (OCP) which guards the system against excessive currents that could damage the power supply and the components it serves. Additionally, the Over-Voltage Protection (OVP) and Under-Voltage Lockout (UVLO) functions protect against voltage irregularities that could otherwise compromise the performance or safety of the application.

The device operates using a high-frequency Zero Voltage Switching (ZVS) resonant topology, which minimizes switching losses and allows for the use of smaller, less expensive components. This leads to a more compact and cost-effective power supply design without sacrificing performance. The NCP1398CDR2G also features an adjustable dead-time control, which contributes to optimal efficiency across various load conditions.

Other notable features of the NCP1398CDR2G include frequency modulation for improved Electromagnetic Interference (EMI) performance, a built-in Brown-Out detector, and a soft-start capability that prevents stress on the power supply during startup. The device also supports a half-bridge or full-bridge configuration, providing design flexibility to accommodate different power levels and application requirements.

The NCP1398CDR2G comes in a compact SOIC-16 package, making it suitable for space-constrained applications. Its operating temperature range from -40°C to +125°C ensures reliability across a wide range of environmental conditions. With its combination of performance, protection features, and design flexibility, the NCP1398CDR2G resonant mode controller from ON Semiconductor stands out as a smart choice for designers looking to create efficient and robust power supply systems.
