Overview

Datasheet Quasi-Resonant Control DC/DC converter and Power Factor Correction converter IC for AC/DC Converter BM1050AF-G ●General Description 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.
The Quasi-resonant system of a DC/DC part contributes to low EMI because PFC operates by soft...
