零件编号 : PMP9757
功能 : Step-Down Converter with Input Overvoltage Protection Reference Design
制造商 : Texas Instruments
This reference design details a power management circuit which is capable to be operated at a supply voltage which is temporarily exceeding the maximum recommended supply voltage of the DCDC converter used.
The protection is achieved by disconnecting the supply voltage and disabling the converter during the overvoltage events. The implementation is based on a completely integrated step down converter circuit enabling a small total solution while still capable of handling up to 3 A at the output.
