PMIC - AC DC Converters, Offline Switchers technology has been a reliable source of power for a variety of applications ranging from computers and other electronics to automotive, industrial and corporate applications. The NCP1051ST100T3 is a low power AC/DC converter designed for applications that require low power, operation from a universal AC input and high efficiency. This product family is designed to provide high power density and low no-load power consumption in a tight space saving design.

The NCP1051ST100T3 Converter module provides a regulated output up to 15 W of output power for industrial and commercial applications as well as for medical equipment, where regulations require high efficiency and low power consumption. The NCP1051ST100T3 is typically used in applications such as computers, laptops, gaming consoles and other electronic or automotive equipment. The module features an on-board MOSFET and is PFC-enhanced with full power factor correction with excellent efficiency. The module also features integrated EMI filters, short circuit and overload protection.

The NCP1051ST100T3 adopts a primary-side-regulation/secondary-side control scheme, wherein power is regulated by detecting the primary winding output current at the primary side and regulating it at the primary side. This scheme eliminates the need for an optocoupler between the primary and secondary sides, thus eliminating the need for additional magnetic component and further minimizing the size of the module. The primary-side-regulation/secondary-side-control scheme is a very efficient power regulation technique that enables high precision and fast loop response.

The NCP1051ST100T3 also integrates an on-board PFC controller, providing excellent efficiency and high-power factor across the entire input range. The NCP1051ST100T3 is suitable for applications that requires high efficiency, low no-load power consumption, small size and low price without compromising performance.

The NCP1051ST100T3 also features comprehensive protection functions. These functions include a total over-current protection as well as over-voltage protection. All these protection functions ensure that the equipment using the module is protected from any fault conditions. In addition, a self-protection function is also included, which can identify and cut-off any abnormal condition.

In summary, the NCP1051ST100T3 is a low power AC/DC converter designed for applications that require low power, operation from a universal AC input and high efficiency. It is suitable for use in applications such as computers, laptops, gaming consoles and other electronic or automotive equipment. Its features includes a primary-side-regulation/secondary-side-control scheme, full power factor correction, integrated EMI filters, short circuit, overload and self-protection functions, which all make the NCP1051ST100T3 a reliable and cost-effective choice in power system design.
