LTC4088  
High Efficiency Battery  
Charger/USB Power Manager  
FeaTures  
DescripTion  
The LTC®4088 is a high efficiency USB PowerPath™  
controller and Li-Ion/Polymer battery charger. It includes  
a synchronous switching input regulator, a full-featured  
battery charger and an ideal diode. Designed specifically  
for USB applications, the LTC4088’s switching regulator  
automatically limits its input current to either 100mA,  
500mA or 1A for wall-powered applications via logic  
control.

The switching input stage provides power to V

Maximum—Transient)  
power sharing between the application circuit and the  
battery charger is managed. Unlike linear PowerPath  
controllers, the LTC4088’s switching input stage can use  
nearly all of the 0.5W or 2.5W available from the USB port  
with minimal power dissipation. This feature allows the  
LTC4088 to provide more power to the application and  
eases thermal issues in space-constrained applications.
