I am using the LM34936 Buck-Boost controller in my circuit based on the WEBench reference design. I have a question in relation to the selection of CBulk. Do you see there being an issue when selecting the CBulk as 39 uF versus the recommended 68 uF in the WEBench reference design? The typical output current is approximately 2 A during normal operation.
The following issue occurred in relation to the MOSFET M1 (see image below). Would you have any thoughts on what could cause this damage? For example would a short between the gate & source cause this as, based on the MOSFET datasheet, the absolute maximum voltage is +/- 20 V while the input voltage in my system is 24 V.
Any help with these points would be greatly appreciated.
All the best,
