2 General descriptions

BL6562 is an active power factor correct controller operating in transition mode, which is mainly used in small power electronic ballast, LED light driver and AC/DC adapter. Realised in advanced BCD technology , BL6562 features ultra-low start-up current and operating current (≤2.2mA @12V). Remote IC DISALBE function can make it work at power saving mode. BL6562 includes an internal highly linear multiplier, able to provide a high power factor in wide-range-mains operation and over a large range load change. The max current of the MOSFET is limited to the upper clamp output voltage of the multiplier. Dynamic and static over -voltage protection, internal supply voltage upper clamp、under voltage lockout and output upper clamp functions can make the system work safely. -400mA/+600mA totem pole output driver is capable of driving large power MOSFET and IGBT.
