Hi,
Using TPS61151 to drive 6 LED with 3 LED in each row.
According to TI application note:
http://focus.ti.com/lit/an/slva258/slva258.pdf
That means we are powering the LEDs >6v at 6.9v to be precise. The Vin of
the chip itself is at 3.4v which is well within the advertised limits.
Please also find our schematic attached.
But once I have my LED string open, the IC heater up and burnt out. Kindly advise what went wrong?
Btw how can I attached my schematic design here? would like to share my schematic over here.
