NCP1124BP65G is an isolated offline AC/DC converter IC which is classified as an AC to DC converter in Power Management ICs. The main application field of NCP1124BP65G is lighting equipments, such as LED lighting, fluorescent lamps, and AC lights.

NCP1124BP65G can provide 65W output power in multiple stage of PFC / LLC or full bridge topology. It supports different kind of power factor correction (PFC) control, like active PFC and bridgeless PFC. NCP1124BP65G has an ongoing short-circuit protection function to prevent the abnormal operation of the system. It also supports multiple type of dimming controls, like digital dimming or hardware dimming and also phase dimming to provide better dimming accuracy and stability.

The working principle of NCP1124BP65G is fairly simple. First, the sinusoidal AC voltage input is applied to the input terminals and it is then converted to DC through a power factor correction (PFC) circuit. The DC output is then provided through the output terminals. NCP1124BP65G also has soft start feature which limits inrush currents while powering up.

The advanced protection feature of NCP1124BP65G include, over-voltage, over-current and over-temperature protection. Over-voltage protection marks a halt in power-on sequences until the input voltage is within a safe operating range. This ensures a safe operation of the system even in high-voltage scenarios. Similarly, over-current and over-temperature protection shut off the supply in case of over-current or over-temperature respectively.

In conclusion, NCP1124BP65G is an isolated offline AC/DC converter, primarily used in LED lighting, fluorescent lamps and AC lights. It supports multiple stage and topology modes with advanced protection features. NCP1124BP65G also supports multiple type of dimming control like digital and phase dimming with soft start feature to prevent overloads.
