BM1051F - Quasi-Resonant Control DC/DC converter and Power Factor Correction converter
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.
Because of putting the current sense resis
