The ICE3A1565L is a monolithic integrated high performance offline power factor correction (PFC) boost converter. It is suitable for active PFC applications such as lighting, home appliances, power supplies and automotive power applications. This power factor correction IC integrates a current control oscillator and a high voltage gate driver, and provides an integrated total solution for offline low power PFC applications.

The ICE3A1565L is specifically designed for applications with input voltage ranging from 85Vac to 305Vac and can deliver an output current of up to 8A. It is designed to work with an external boost inductor and the power stage is designed to have the highest power density for an offline PFC. Its wide input range makes it suitable for applications around the world.

The ICE3A1565L has several integrated protection features including soft-start, over-current protection, over-voltage protection, under-voltage protection, fast over-temperature protection, and thermal warning signal output. In addition, the IC provides cycle-by-cycle current limitation. These features make the ICE3A1565L an ideal solution for cost-sensitive and reliable offline constant voltage PFC applications.

The ICE3A1565L operates in the boundary mode, with active switching of two switches [discrete or an integrated MOSFET] which produces a duty cycle depending on the input voltage. The active switching allows for dynamic control of the feedback gain and the output voltage. The IC features DIP-7 and TSSOP-8 packages, making it suitable for use in a variety of end products. The IC can be connected either in or out of the actual circuit and can be mounted on a heatsink.

In summary, the ICE3A1565L is a simple, efficient and reliable IC for off-line PFC applications. It integrates a current control oscillator, high voltage gate driver and over-current protection features, allowing for integration of the entire active PFC power supply design in a single IC. The ICE3A1565L is ideal for cost-sensitive and reliable applications such as lighting, home appliances, power supplies and automotive power applications.
