Part Number: LM2655 Tool/software: I am using LM2655MTCX-ADJ to make 5V from 12V. I drive the SD/SS terminal with SN74LVC1G07DBVR to delay the startup, but the current situation where the LM2655MTCX-ADJ breaks when shutting down is happening.
The data…
Yes, we are working to find an alternative model that may fit this part or else we will need to look at other options like bench testing. Will continue updates via email chain.
Part Number: LM2655
Recently we have several electronics that don’t pass the production tests due to the fact that the + 3.3V made by the LM2655MTC-ADJ cannot start. The schematic below has been used for years on almost all our designs:

Hi John,
There should be no reason for device to have issues with light load conditions. As you noticed under light load conditions the low side FET will be in switched on state and if this FET is properly sized device should operate without any issues…
Other Parts Discussed in Thread: LM2655 I'd like to do a verification of the loop compensation of an existing LM2655 design, but it seems the data sheet information is incomplete. Anyone left from National who knows this device?
The small signal model…
