Description
General part information
BM1050 Series
BM1050AF 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. BM1050AF built in a HV starter circuit that tolerates 650V. Because of putting the current sense resistors externally both the PFC part and the DC/DC part, IC enables power supply design free.In the PFC part, IC adopts peak current control operation. Suitable application is proposed by a various protection circuit, such as the multiplier with a revision circuit on the AC voltage falls, the load regulation revision circuit, and the maximum power feed-forward circuit, etc. Moreover, the frequency hopping function is built in and it contributes to low EMI.You can choose from a variety of power and topologyevaluation boards.
