Other Parts Discussed in Thread: TLC59116
To Whom it May Concern,
Why is such a capable voltage regulator, the fast-transient response, 1.5A rated, TPS7A4533KTT used on the eval board? The LEDs are driven by Vin and I do not see a mechanism to switch them over to the TPS7A4533KTT. The datasheet stipulates a TLC59116PW current draw (Icc) of 37mA at 5.5V with all channels on and almost full LED sink current (Iout). Was the design originally capable of/designed to support the LEDs from the voltage regulator? Or is this supporting protection circuits setup against the output channels and/or LED surge currents.
