The MOSFET is also protected at start up by the power limit (FET SOA protection) feature. At start up, the assumption is that the output load is not applied (so at start up the 168W load is disabled by the TPS2492 PG pin) and that the only start up FET…
Hi Brian,
Unfortunately you cannot change the insertion time of the LM5069. Best solution is to switch to TPS2493. It is 60V capable with power limiting. However, Ctimer only affects fault time. You can evaluate this performance using the EVM as shown…
