Product Summary

The MB39C312PVK-G is a 4ch system power management IC. The MB39C312PVK-G consists of 2-ch DC/DC Converter and 2-ch Charge pump. The DC/DC converter has excellent line regulation with the feed-forward method. Moreover, SW FET and phase compensator (Buck) is included, so that BOM can be reduced. It is most suitable for large size LCD panel power supply. The applications of the MB39C312PVK-G include TFT LCD panels for LCD TV sets and monitors.
