TLD55012BUCKDEMOTOBO1

TLD55012BUCKDEMOTOBO1 is an evaluation board for high power applications with the TLD5501-2QV product. TLD5501-2QV is an AEC qualified dual channel buck DC-DC controller suitable for constant current (LED driver) and constant voltage applications. The default configuration of the evaluation board is “Dual buck parallel voltage regulator” in which the two channels work in multiphase to provide up to 80W to the load with an efficiency above 90%. The board can be also configured for different scenarios such as “Dual buck independent voltage regulators”: the two channels work as two independent constant voltage supply. “Dual buck independent current regulators”: the two channels work as two independent constant current supply (LED application).“Single buck independent current regulator plus single buck independent voltage regulator”: one channel work as constant voltage supply and the other one as constant current supply (LED application).
