NCP1200AP40G is part of a family of advanced, multi-phase buck converters from ON Semiconductor. The NCP1200AP40G is a highly integrated, high performance, high efficiency synchronous buck switching regulator controller. It is designed to provide excellent light-load efficiency and fast transient response for systems requiring high current and fast load switching. It offers fast response, high efficiency, robust EMI filtering capability, and immunity to supply voltage variations. This makes the NCP1200AP40G an ideal choice for a wide range of point-of-load (POL) applications.

Application Field of NCP1200AP40G

NCP1200AP40G is suitable for applications that require high-performance, high-efficiency synchronous buck converter. These applications include, but are not limited to: computers, networking, power distribution architectures, telecommunication equipment, household appliances, automotive systems and many others. The NCP1200AP40G is ideally suited for use as a point-of-load (POL) regulator. It is also suitable for applications that require tight load regulation and low output noise, such as set-top boxes, digital video systems, and medical systems.

Working Principle of NCP1200AP40G

NCP1200AP40G is a high-performance, high-efficiency, intelligent buck regulator controller. It is designed to work in multi-phase there or four-phase applications, providing excellent light-load efficiency and fast transient response. It supports adjustable output voltage control and constant/variable switching frequency. It operates in either continuous or discontinuous conduction modes. It also has a power-good (PG) output signal and an auto-discharge feature.

The NCP1200AP40G features an analog-controlled valley current limit. This limits peak valley current and thus reduces ripple current, which allows for higher efficiency and better thermal performance. The NCP1200AP40G is optimized for wide input voltage range and can support higher input voltage levels. The chip has a programmable under-voltage lockout (UVLO), over-voltage protection (OVP), and over-temperature protection (OTP). It also has a smart-based compensation for impedance sensitive applications.

The NCP1200AP40G supports a wide range of applications. It offers adjustable frequencies from 100kHz to 63 kHz, with a wide spread of phases, allowing the selection of higher switching frequency or multi-phase applications. This allows for lower switching losses, faster transient response and higher output power. In addition, a regulation tolerance of +/-1% of the minimum load value is offered, which allows for tight regulation.

The NCP1200AP40G is a highly integrated and complete power-management solution. It is designed to provide a wide range of features and flexibility to meet the needs of demanding power-management applications. It is designed to reduce design time and cost, while delivering a robust and reliable power management platform.
