The NCP1240GD065R2G is a high efficiency buck converter belonging to the family of AC/DC converters, offline switchers and PMICs. This product is ideal for applications requiring high efficiency, ultra low noise and superior power density performance. It is designed for high frequency low noise operation and is well suited for applications such as servers and storage, set top boxes, notebooks and gaming systems.

The NCP1240GD065R2G offers a wide input voltage range of 4V to 42V, perfect for highly efficient power supplies used in automotive and industrial applications. It consists of an internal synchronous rectifier and provides up to 98% efficiency. Thanks to its integrated synchronous rectifier, it offers low ripple & noise performance. As opposed to other offline switching converters, this product is well suited for very low output voltage applications thanks to its low quiescent current.

Its superior performance makes it particularly well-suited to highly regulated systems, such as audio amplifiers, cellular phones, telecom systems and PC motherboards. It is tailored for high current applications and it provides up to 400kHz switching frequency. The internal MOSFETs of the NCP1240GD065R2G also reduce external components and minimize the size of applications. Its high power density allows system designers to achieve greater power density in less space.

The NCP1240GD065R2G works on an inverter principle. It takes a low voltage DC input, increases the voltage level and then uses that high voltage DC output to drive a power MOSFET switch which switches the polarity of the output. The MOSFET then takes the high voltage DC output and applies it to an inductor and a diode, generating a pulsating current in the load. By doing this, it efficiently converts a low voltage DC input to a high voltage DC output.

The NCP1240GD065R2G incorporates advanced protection features such as input UVLO, output over voltage protection, thermal shutdown and short circuit protection. All the protection features ensure the converter is reliable in harsh environment and provide a long-term stable performance for your application. The NCP1240GD065R2G is optimized for low noise and high efficiency and is designed for a wide range of applications where space is a premium.
