isolated-gate-driver

I am using the ADuM422 isolated gate driver (Analog Devices) in my design, and I am repeatedly encountering failures of the IC. Initially, we suspected that the device was getting damaged due to a surge at startup, since the RBOOT resistor was not included in the original design. Based on this...

I am debugging a DC-DC full-bridge converter where the power stage and gate drive operate correctly in open-loop, but the gate driver ICs repeatedly fail when the control loop is closed. I am looking for insights into what mechanisms could cause this behavior. System Overview 1. Topology...
