2 Description
The H-Bridge architecture is among the most efficient buck-boost topologies for high current applications.
TLD5190 provides digital and analog dimming control and 2 flags for diagnostic.
The TLD5190IVREG-EVAL is an evaluation platform for the TLD5190QV as LED driver or voltage regulator.
The default configuration
can be increased up to 6 A by changing RSHO. If higher currents are needed, the output filter has to be bypassed.
Figure 2 TLD5190QV as LED driver
By reconfiguring a few solder jumps, the board becomes a powerful voltage regulator.
Figure 3 TLD5190QV as voltage regulator
On the board, in addition to the TLD5190QV device the following are present:
 Trimmer to adjust output voltage when set as voltage regulator

Trimmer to adjust output current
 Two LEDs showing TLD5190QV faults status (EF1, EF2)
