Hundreds of Watts, 60V In or Out: Synchronous 4-Switch
Buck-Boost Converter is Easy to Parallel to Minimize
Temperature Rise
Keith Szolusha The LT3790 is a 4-switch synchronous buck-boost
DC/DC converter that regulates both constant voltage
and constant current at up to 98.5% efficiency using
only a single inductor. It can deliver hundreds of watts
and features a 60V input and output rating, making it an
ideal DC/DC voltage regulator and battery charger when
both step-up and step-down conversion are needed.
A single LT3790 converter can deliver high
power due to its synchronous switching
topology, but eventually the switching
and/or conduction losses at higher power
can overwhelm a single converter with
excessive board heating. Although heat can VIN
