Hi Sir,
When the MOSFETs are not welded, the HG will keep high since there is a boot cap charge path that will charge this. Have you tried with high power MOSFETs? or you can try with our TPS92641EVM.

Part Number: TPS92641 Hi team,
I have a question about the bootstrap diode.
I believe that voltage rating of the bootstrap diode requires more than Vcc(9.14V max) of TPS92641. However, the TPS92641EVM employs 100V/1A Schottky diode. Does the bootstrap diode…
Part Number: TPS92640 Other Parts Discussed in Thread: TPS92641EVM , Hi
Our customer are evaluating this device with TI-EVM(TPS92641EVM).
And they found some phenomenon that we do not understand why this device operate such behavior as bellow.

Dear Sir,
We want to control the LED by adjust IADJ voltage linearly. After testing the TPS92641EVM , it will show blinking when the IADJ voltage around 50mV~100mV. can this situation be fixed? thanks.

Our customer evaluates TPS92641 with TPS92641EVM. And they modified the EVM to test the analog dimming.
IADJ pin : Radj1=10kohm, Radj2=15kohm, VREF pin is opened. And it is connected to the DC supply…
Other Parts Discussed in Thread: TPS92641EVM Hi everyone,
I'm working on a project related to Visual Light Communication (VLC). We did some initial questions in the following thread link and answer was very useful!

Other Parts Discussed in Thread: TPS92641 , TPS92641EVM Hello,
Is there a recommended frequency range when using UDIM for PWM dimming of TPS92641? In the data sheet I can only find 200 Hz (mentioned in figure 12 on page 8):

Other Parts Discussed in Thread: TPS92641EVM , TPS92641 Hi, I want to use a TPS92641 to drive a LED series with maximum 1000mA at 24V, using both analog and SDIM PWM dimming, using a similar schematic to the TPS92641EVM (and the same 48V Vin). I appreciate…
