Part Number: TPS549A20 Other Parts Discussed in Thread: TPS53915 , TPS53819A How do I find the PMBus device ID for the TPS549A20?
The command code 0xFC is used for PMBus self-discovery for the TPS549A20. The expected response is either 0x0089 or 0x0090…
Part Number: TPS53819A Hi team,
I have a question about the OCP functionality.
The DS says " TPS53819A has cycle-by-cycle overcurrent limiting control. The inductor current is monitored during the OFF state ."
My question is that how the device…
Hi,
For the level of accuracy needed, we recommend the TPS546D24A
With the TPS546D24A, You can program the Vout resolution upto 0.244mV.
For TPS546D24A, using a Vout of 1V as the example, the accuracy is +/-8mV from -40C to 150C junction temperature.…
Part Number: TPS53819A Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Hi,TI power expert:
When I do the simulation of TPS53819A using Pspice model, I set the output voltage 5volts, and the Feedback resistor is the same…
Part Number: TPS53819A Other Parts Discussed in Thread: TINA-TI , TPS53819 Tool/software: TINA-TI or Spice Models Hi, TI expert:
When use TPS53819 PSPICE models with CSD86360 PSPICE models, the output set to 5v, I found in steady state, there was a low…
Part Number: TPS53819A Other Parts Discussed in Thread: TINA-TI Tool/software: TINA-TI or Spice Models Hi, TI' s expert:
I want to simulate 5V volts start up using TINA software, so change the feedback resistors of PR6 from 10K to 1.37K. but after…
Kent,
From what we can tell, FUSION is attempting to read the MFR_SPECIFIC_42 command of the TPS53819A by error. Some TI devices use MFR_SPECIFIC_42 to identify which device they are to FUSION, but that should not affect the ability to save and restore…
Part Number: TPS53819A I'm using the TPS53819a in an application with 3.3V in and .066V out at 20A. VDD is driven at 5V. The switching frequency is set to 525kHz. The problem I'm seeing is that the switching waveform does 2 consecutive pulses, each with…
