Infineon Technologies TLD5501-2 Buck Demonstration Board
Infineon Technologies TLD5501-2 Buck Demonstration Board (TLD5501-2 BUCK DEMO) is an evaluation board for high power applications with the TLD5501-2QV LED lighting driver Integrated Circuit (IC). The TLD5501-2QV IC is an AEC-qualified dual channel buck DC-DC controller suitable for constant current (LED driver) and constant voltage applications. The board optimizes high power LED applications. Users can drive LEDs efficiently with a dual buck parallel voltage regulator topology, delivering over 80W with 90%+ efficiency. This Infineon board can also be configured for other topologies, including dual buck parallel current regulator, dual buck independent voltage regulators, dual buck independent current regulators, or single buck independent current regulator + single buck independent voltage regulator.
