产品概述
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 in as a voltage regulator.
Capable to drive multiple LED functions (E.G. LB, HB, DRL) with a single DCDC converter for a more compact and efficient design
