Other Parts Discussed in Thread: TPS40051
Hi.
We put on a board a TPS40051 to replace a TPS40055. The two components are very similary and we use the design example (fig 16 from the datasheet of the TPS40055).
In this case, all TPS are destroy and the mos connected to HDRV pin too.
If i compare the two design exemple (TP40055 VS TPS40051), we don't have the diode D2 connected to the SW pin. If this diode is missing, the TPS40051 is destroyed ?
Thank for your answer.
