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.
