LTC3899 60V Low IQ Triple Output Buck-Boost Synchronous Controller
Analog Devices, Inc.
The Analog Devices LTC3899 operates from an input voltage of 4.5 V to 60 V during start-up and maintains operation down to 2.2 V after start-up. The one boost and two buck converters can produce output voltages up to 60 V with high efficiencies. In applications where the input voltage may exceed the boost regulated output voltage, the LTC3899 keeps the synchronous boost MOSFET on continuously so that the output voltage follows the input voltage with minimal power loss.
