DESCRIPTION  
FEATURES  
The LT®1513 is a 500kHz current mode switching regula-  
tor specially configured to create a constant- or program-  
mable-current/constant-voltagebatterycharger.Inaddition  
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  
currentsensecircuittobegroundreferredandcompletely  
separatedfromthebatteryitself,simplifyingbatteryswitch-  
ing and system grounding problems. In addition, these  
topologies allow charging even when the input voltage is  
lower than the battery voltage. The LT1513 can also drive  
a CCFL Royer converter with high efficiency in floating or  
grounded mode.

APPLICATIONS  
Maximum switch current on the LT1513 is 3A. This allows  
battery charging currents up to 2A for a single lithium-ion  
cell. Accuracy of 1% in constant-voltage mode is perfect  
for lithium battery applications. Charging current can be  
easily programmed for all battery types.
