Part Number : PMP9757
Function : Step-Down Converter with Input Overvoltage Protection Reference Design
Manufacturer : Texas Instruments
Pinout :
Description
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.
