High power charge controller interfaces with any switching regulator
Linear Technology's LTC4000 is a high voltage controller and power manager that converts virtually any externally compensated dc/dc power supply into a full featured battery charger. It is capable of driving typical dc/dc converter topologies, including buck, boost, buck boost, SEPIC and flyback.
The device offers precision input and charge current regulation and operates across a wide 3 to 60V input and output voltage range, compatible with a variety of different input voltage sources, battery stacks and chemistries.
Typical applications include high power battery charger systems, high performance portable instruments, battery backup systems, industrial battery equipped devices and notebook/subnotebook computers.
