Hello all. Thanks for taking up your time to read my post.The specs of TI TPS75105YFFR LED driver as the datasheet of http://www.kyniix.com/uploadfiles/pdf9675/TPS75105YFFR.pdf says "constant current sinking" capability is 60-mA.(LED Power supply voltage up to 15 Volts, and Vcc=3.0V to 5.5 V )My understanding is if Sink current is low, then its better as it will not heat-up my LED driver chips.1- I want to understand What is the importance of High (or Low) LED driver Sink current?2- Why we do not talk about sourcing Current instead?Any comments?
