LTM4641 TechClip - Output Overvoltage Response
2017年09月18日
To protect high value loads such as FPGAs, ASICs, and microprocessors, the LTM4641 responds to an output overvoltage condition by immediately disconnecting the input supply and activating a crowbar FET between the output and ground. These actions limit the peak output voltage excursion to 20% of the programmed output voltage under a full load and no load condition. Input overvoltage protection may be extended upward by adding a high voltage LDO such as the LT3010 to the LTM4641. The input surge performance shown reflects the circuit schematic.
