DESCRIPTION
The LT ®1513 is a 500kHz current mode switching
regulator specially configured to create a constant- or programmable-current/constant-voltage battery charger.
In addition to the usual voltage feedback node, it has a current sense feedback circuit for accurately controlling output current of a flyback or SEPIC (Single-Ended Primary Inductance Converter) topology charger.
These topologies allow the current sense circuit to be ground referred and completely separated from the battery itself, simplifying battery switching and system grounding problems.
In addition, these topologi...
