Battery Charge Controller IC is rated up to 60 V.
Capable of driving typical DC/DC converter topologies, LTC4000 converts externally compensated DC/DC power supply into full-featured battery charger. It operates across 3-60 V input and output voltage range; is compatible with various input voltage sources, battery stacks, and chemistries; and preferentially provides power to system load when input power is limited. IC also controls external...

Buck/Buck/Boost DC/DC Controller targets automotive systems.
With quiescent current rating under 55 Ã-µA per channel, triple output LTC3859 maintains all output voltages in regulation during automotive cold crank conditions. It operates from 4.5-38 V input during start-up and maintains operation down to 2.5 V thereafter. While synchronous boost converter can produce up to 60 V output and run at 0% duty cycle (synchronous switch ON), 2 step-down...
