  Part Number: LM5010 Hi Andy, thanks for the reply. Continuation of previous inquiry I changed power suuply, I was able to output 15V. I used 500 ohm as a dummy load, Is there a way or formula to validate the 500 ohm? Thanks very much -yuuki

  TI Thinks Resolved

  Part Number: LM5010 Lm5010 works as 15V converter for MOSFET drivers, Vin 48V. LM5010 is followed by the Efuse TPS6623 working as protector, just in case LM dies and 48V input voltage propagates to rest of the system. The 15V is used to make 5 and 3V3…

• LM5010: Is this part short circuit safe?

  TI Thinks Resolved

  Part Number: LM5010 The short protection circuit for LM5010 is a bit unusual - looking at off-time flyback current to turn off transistor not on current cycle but on next cycle. In practice, is this part short circuit reliable?
