TLD5501-2 BUCK DEMO
Evaluation board for high power led applications with the TLD5501-2QV product.
The TLD5501-2QV BUCK DEMO is optimized to drive HIGH POWER LED applications.
The default configuration of the board is “Dual Buck Parallel Voltage Regulator” in multiphase topology that allows to provide up to 80W to the load with an efficiency above 90%.
The board can be configured to different topologies like “Dual Buck Parallel Current Regulator”, “Dual Buck Independent Voltage Regulators”, “Dual Buck Independent Current Regulators” and “Single Buck Independent Current Regulator + Single Buck Independent Voltage Regulator”.
The board contain a 2x7 pin header to connect the TLD55xx MICROKIT (SP001802790) board. This interface allows to control the TLD5501-2QV BUCK DEMO board through a LabVIEW GUI installed in the PC.
