Part Number: TPS560430
Hi,
I have 10 to 30V input Voltage application with 1 to 200mA and am using the TPS560430 regulator.
My problem under very light load is that if I simulate input transients between 0 (open) and 30V my regulator suddenly dies. I managed make it more robust by adding a resistor of about 40 Ohm in series to the bootstrap resistor. Unfortunately if I tried hard enough I still can get the regulator to die.
this is the schematic I use. (no load for testing)
any suggestions welcome.
regards,
Andreas
