MC33680 Dual DC−DC Regulator for Electronic Organizer
The MC33680 is a dual DC−DC regulator designed for electronic organizer applications. Both regulators apply Pulse−Frequency−Modulation (PFM). The main step−up regulator output can be externally adjusted from 2.7V to 5V. An internal synchronous rectifier is used to ensure high efficiency (achieve 87%). The...
