Part Number: TPS543C20 Other Parts Discussed in Thread: TPS543B20 , , Tool/software: Hello
I designed a DC/DC for 12V to 1.2V 20A load. The problem is that when I just use a 0.5ohm load which is around 2A, it is fine, but when I increase the load to…
Part Number: TPS543C20 Tool/software: Hi,
Am using the TPS543C20RVFT part in my device to convert 12V to 3.3V voltage, how can i calculate the ILIM resistor value.
Got the below formulae from datasheet, but am unable to get how this Rlim is choosen…
Part Number: TPS543C20 Tool/software: Dear Team,
In the below mentioned thread it is mentioned not to make feedback resistor DNP.
TPS543C20: Sense pin connection confirmation
But datasheet suggest when load has sense option we don't need to connect…
Part Number: TPS543C20 Other Parts Discussed in Thread: TPS546E25 , , TPS546D24A Dear Team,
I want to know about is there any alternate part available for the following conditions. I have 2 major Condition.

Part Number: TPS543C20A Other Parts Discussed in Thread: TPS543C20 I am trying to simulate the TPS543C20 under transient conditions in Pspice for TI. To do this I would like to use the circuit and steady state model in TPS543C20RVF_TRANS and add a current…
Part Number: TPS543C20 I am using TPS543C20RVF in my design to generate 5V from an input 12V. The schematic is attached for rweference. The output comes out to be 1.3V and not 5V. I have verified each and every component and inputs there seem to be no…
Part Number: TPS543C20 Other Parts Discussed in Thread: TPS548B22 , , TPS546B25 , TPS546E25 , TPS548D26 Tool/software: Dear Team,
It is found that the part TPS543C20RVFT has Lead over threshold. Please confirm if this is true and provide alternate part…
Part Number: TPS543C20 Tool/software: Dear Team,
Please confirm the below schematics connection
We have dedicated sense pin from processor, VCCINT_SNS_P & VCCINT_SNS_N. So can we connect that directly to RSP &RSN pin of this regulator with output…
Part Number: TPS543C20 Tool/software: Hi,
I read in the datasheet of TPS543C20 that it employs "Fixed-frequency modulation" and that it is a "true fixed frequency converter".
It is not clear to me what this means. Is the frequency fixed or does it…
Part Number: TPS543C20 Tool/software: Hi Team, Is there any Stackable DC DC converter with -55 to 125 temperature range?
Thanks and regards, Maharajan P
