Part Number:TPS54622
Hi,
I wanted to implement dynamic management on TPS54622 basing on TI doc SLVA861–December 2016"How to Dynamically Adjust Power Module Output Voltage"
The schematics is attached . Input voltage is 15V. Output voltage is 12V which manag(Please visit the site to view this file)d within range +-10%.As DAC I am using MCP4725. In general management is working. However I have problem with current transient.When I running transient from 1Amp -> 0Amp during tens microsecond the TPS54622 is burn out: input and output of the chip are short connected to GND pins. Could you hint what can be a problem?
Thank you
