Hi Gareth,

No. The timer cycles only for over current fault but not UVLO, OVP events

Hi Rakesh,

may i know LM5069 pin10 GATE pin. Can use RC delay to adjust soft start? like the as below schematic R31 & C40.

Hi Tommy,

Yes, the RC should be in series and then connected to GATE pin as shown below. This way, the R does not affect the turn-off speed of the MOSFET.
