Hi,
We are attempting to use the TPS61187 for driving 60 white leds at 20mA, and chips are failing after a while.
Here is the schematics, LEDs have been left out, but are exactly as specified in the datasheet and evm.
Input voltage is 12V which is supplied over a 1m to 1.5m long power cord. PWM is applied with duty cycles ranging from 0 to 1.
Is there anything that comes to mind that would make the TPS61187 fail over time (ranging from DoA to weeks or months)?
