Part Number: TPS28225
3-State Input with Single Pin Controller
The TPS28225 has a 3-state input that allows the controller to use a single pin to drive two output FETs as well as set both outputs low by setting the PWM pin to high impedance in the 3…
Part Number: TPS28225-Q1 Hello,
I have the same issue. I am designing a boost converter and I am using the IC to drive to MOSFETs. The converter works as intended and it boosts the voltage. The problem occurs when the input voltage rises above the output…
Part Number: TPS28225 Hello Everyone,
I made a design using the TPS28225, but after ordering the boards, I realized both the gate drive voltage and switch node voltage ratings were inadequate for the application.
Gate drive voltage requirement is 12 V…
Hey,
I am going to close this thread under the assumption that this has been resolved.
If this has not been resolved, please reopen this thread and reply here with the current status of the project and any questions that you have.
Thank you,

Hi Ovidiu,
Please see below for my answers.

We have a FAQ that walks through correctly calculating the needed bootstrap capacitance. We also have an FAQ that covers…
Part Number: TPS28225 Hello team,
My customer wants to use TPS28225 with 3.3V of PWM input with PWM mode only.
On the datasheet, electrical characteristic table, it says LOW threshold is 1.0V and HIGH threshold is 3.8V when PWM=5V.
On 7.3.4 section…
Part Number: TPS28225 Hello team,
On the datasheet, there was only typical value for the dead time of TPS28225. Do you have MIN and MAX value?
Best Regards, Kei Kuwahara
Part Number: TPS28225 Hello team,
On the datasheet 7.3.4.2 there is note about external resistor between PWM and GND.
What if I don't put any resistor between PWM and GND? I believe it will disable 3-state mode, but will TPS28225 operate normally?
