ZHCSMU0D July 2009 – December 2020 TPS23753A
Take special care in selecting the converter switching MOSFET. The TPS23753A converter section has minimum VC operating voltage of approximately 5.5 V, which is reflected in the applied gate voltage. This occurs during an output overload, or towards the end of a (failed) bootstrap start-up. The MOSFET must be able to carry the anticipated peak fault current at this gate voltage.
