Other Parts Discussed in Thread: TPS61150 , TPS61150A I have been using the TPS61150 for an LCD with 2 Strands of 4 White LED's each. The voltage ends up around 14V with the current in each strand set by Vset/Rset * 920 or 1.229 / 54.9K * 920 = 20 mA each…
Other Parts Discussed in Thread: LM3532 , TPS61150 CC LED driver, can you help me find the right TI part?
Integrated boost converter to provide enough voltage for 10 LEDs in series per channel (33V+).

Other Parts Discussed in Thread: TPS61150 , TPS61150A , TPS61151 Hi,
Using TPS 61151 to drive 6 LED on one of the two rows. We have a strange effect. If we disconnect the display (the string of 6 LEDs) the chip blows up. I can measure a low resistance approx…
If you only have 1 LED per string, then I suggest the TPS60230, tying two strings together to get 30mA.
If you have 2 LEDs per string and only 2 strings, then I suggest the TPS61150.

Hi Paul,
Yes, and the unused pins can be left floating.
One question: How about input voltage range? If it's not too low, how about single channel device, such as tps61500?
