Hi Yamamoto-san,
Shunsuke Yamamoto said: May I know how to calculate the output current on IPROPI pin when high side current is 1A?
In the DRV824x-Q1 current sensing is done on HSFETs only. So IRPOPI always has the scaled down representation of the high…
Hi Ivy,
So it looks like no shoot through is happening, it is important to look at GHx to SHx when trying to view something like deadtime. I think those spikes might be present because the customer is using 1A for IDRIVE. 1A might be too much for the…
Part Number: DRV8350 Tool/software: Dear Ti team
First, we're using "DRV8350R" part.
I have a question about this part.
IDRIVE Setting.
As you can see 9.2.1.2.2 IDRIVE Configuration in datasheet
we can calculate IDRIVEP, IDRIVEN values…
Hi Tao, Thank you for your reply.
So, does auto PFM mode mean that it's PFM when the output is 100mA, and PWM when the output is 1A? In other words, do these curves show the transition from PFM to PWM to PFM?
I'm checking whether the transition from…
Part Number: LM5020 Tool/software: Hi,
Vin=36-75V
Vout1=12V
Iout1=1A
Vout2=12V
Iout2=3A
Fsw=100KHz
We are using the LM5020 as a flyback converter. The MOSFET seems to be trying to turn on during the off period, and the voltage across the drain-to-source…
Part Number: UCC28951-Q1 Other Parts Discussed in Thread: UCC28951
Tool/software:
Hello Mike,
Two output windings are connected in series. Output is regulated to 26V.
Below waveform is before it enters regulation, voltage is around 300VDC, load current…
Hi Miguel,
Miguel Aguirre said: We are working on an application were the power line must be a square or sinusoidal wave between 50KHz to 100KHz (under development yet)
The THVD8000 has a bandpass filter on its receiver, so if you do use the 5MHz carrier…
Part Number: CC2340R2 Tool/software: Hi Team,
We are creating a project for the LE core complete design using QDID 201833, which is listed in SIG by Texas Instruments Incorporated. The QDID 201833 covers the LL and GATT layers, and product owner has…
Hi Jarrod,
That's a good point. I checked in design. In VCA die, SDOUT buffer is working on 3.3V supply. So when SDOUT is driven by VCA die, it will be 3.3V and when driven by ADC die, it will 1.8V. But since the SDOUT of two dies are shorted and the…
Part Number: BQ25720
Tool/software:
As we know,BQ25720 supports both IinDPM and Two-Level Adapter Input Current Limit(Peak Power Mode),so what‘s the difference and relationship between them?
If the IinDPM is set to 1A,and the ILIM1 in the feature…
