TLD5542-1QV
The TLD5542-1QV is a synchronous H-Bridge DC-DC controller with built in protection features and SPI interface
The H-Bridge architecture is among the most efficient buck-boost topology for high current applications. The device can work in current mode (E.G. LED driver, battery charger) or as a voltage regulator. Capable to drive multiple LED functions (E.G. LB, HB, DRL) with a single DC-DC converter for a more compact and efficient design.
