Other Parts Discussed in Thread: TPS53819A Starting with the TPS53819A reference simulation model, I changed the bottom feedback resistor from 10K to 2.23K in order to create a 3.3V output. I also changed the load resistor from 60m-Ohms to 600m-Ohms. The…
Other Parts Discussed in Thread: TPS53915 , TPS53819A Dear Sir
We would like to design TPS53819A and TPS53915 for PMBUS solution
If we don't connect PMBUS interface ,Could I use these by H/W setting or I have to program register ?
Thanks
Other Parts Discussed in Thread: TPS53819A How do I change the switching frequency for the TPS53819A in the TINA simulation? I can see how to open up the macro, and I can edit the macro to change FREQ_SEL=1 (325KHz) to FREQ_SEL=4 (600KHz) but there is…
Other Parts Discussed in Thread: TPS53819A I'm working on an I2C regulator TPS53819A with DM8168 chip, I wonder if there is an existing driver for that regulator or a similar one that I can build on.
Thanks,

Hi,
One question for Vout margin, how to calculate the final output voltage when to use Vout adjustment and margin?
According to datasheet example, setting fine adjustment to +9% and margin to +12% changes the output by +22.08%, I am no idea how to get…
Issue 1 - unstable when Vtrip < 0.2V
--------------------------------------------------
The data sheets specify Vtrip min 0.2V. We initially had 10k to GND on this pin, i.e. 0.1V. That made the controller extremely unstable, particularly in FCCM mode…
Hello,
TI offers a variety of buck controllers that may work in place of the TPS53015DGS.
As a drop-in replacement (without adjustable soft-start), I would recommend the TPS53014- https://www.ti.com/product/TPS53014
If a DCAP/DCAP2 topology is desired…
Hello Sophie,
Thanks for your interest in TI FETs. I was able to get the TPS53819A PSpice Transient Model ( SLUM349A.ZIP (40 KB) - PSpice Model in the TPS53819A product folder ) to work with the CSD86360Q5D PSpice model ( SLUM349A.ZIP (40 KB) - PSpice Model…

The TPS53819A does not have an on-board ADC and does not support telemetry monitoring. The list of the supported commands is
For a device with Input Voltage, Output Voltage, Output Current and Device Temperature telemetry, you can look at…
