Hello Rakesh,
I have attached the scope capture and schematic.
Perhaps, the solution could be to set PGOOD threshold lower than under-voltage threshold? In this case, the TPS25944A will stop before de-asserting PGOOD and therefor not reverse conduct…
Part Number: TPS25200 Other Parts Discussed in Thread: INA219 , BQ24210 , TPS25944A
Hello all,
I am trying to add input protection to my circuit. Shown above is a snippet of my circuit. The input power source (+VIN_UP) will either be a 5W solar…
Part Number: TPS25942A Other Parts Discussed in Thread: TPS25942EVM-635 Hello,
I have downloaded and used the TPS2594x Design Calculation Tool (TPS2594x-Calculation Sheet V1p0.xlsx). There are Imax and Ilimit columns, but Imax is not mentioned in the…
Other Parts Discussed in Thread: TPS62153 , TPS62410 I am using the TPS62153 as a pre-regulator that steps +12V DC down to +5V DC as an input for a secondary buck regulator which makes dual 3.3V supplies. The design appears to work as expected, but after…
Part Number: TPS25942A Hello,
I am planning to use this IC for my application and I have a couple of questions:
1- The input to my circuit (which this IC is part of it) is 12V DC. I have two lines inputs: 1- onboard power 2- Shore power. Both powers…
