I have a created a circuit from the Sensortile reference design and the MCU and the step down transformer both overheat, I am thinking the BGA pattern on the STM32 is off and there is a short drawing alot of current?
BOOT0 is ground
Reset is pulled low
the SWDIO and SWDCLOCK line are connected directly via a pinout to the nucleo board
The attached step down and induction circuit have worked perfectly with previous TI MCU designs.
Any insight into where I may have connected the MCU up incorrectly or not used enough decouplers?
