battery backup
A new class of linear regulator has been developed for battery backup applications. It eliminates both the losses associated with steering diodes, the glitches and battery-to-battery cross conduction inherent in MOSFET switching schemes and the poor regulation inherent in dual regulator schemes previously used for this purpose. See the comparison detailed in Table 216.1.
