Additional preview pages of the BM1051F datasheet.

BM1051F is compounded LSI of Power Factor Correction converter (PFC) for harmonic solution and DC/DC converter (DC/DC).

Because DC/DC operates on Quasi-resonant method, DC/DC contributes to Low EMI.

BM1051F built in a HV starter circuit that tolerates 650V.

-resonant circuit + PFC circuit.
Built-in HV Starter circuit.
Low consumption current (typ.10uA) when starter circuit is OFF.
Quasi resonant circuit Max operating frequency(120kHz) Frequency reduction function Over-current limiting variable function Pulse-by-pulse over-current protection circuit Built-in Soft start Voltage protection function (brown out) during low input ZT pin Over Voltage Protection Output overload protection (auto recovery /latch switching enabled) 250nsec Lea.
