Part Number: TPS54541 Hi,
I am designing a buck to convert 9v~32v DC input to 4.5v. Max. load is about 20w, which means max load could reach around 4.5A.
System load of my product may be dramatically changed from <500mA to max. load so the voltage drop…
Part Number: TPS54541 Other Parts Discussed in Thread: LM5085 Hi
Our 5 channel battery charger for marine radio beacons consists in 5 constant current channels at 0.4A each Also temperature is quite high (would be fine to go with external mosfet solution…
Part Number: TPS54541 Hi,
We have used the TPS54541 IC for +12V & -12V generation. It is working.
But when we probe the -12V regulator for current measurement, the IC output was shorted with Ground. (Just Ammeter connected as per diagram, and powered…
Part Number: TPS54541 Hi Team,
my customer has issues with EMI performance and to early drop out of the device. Now he wants either improve the design or needs a better suggestion for a other Buck-converter:
Unfortunately, the results of the TPS54541…
Part Number: TPS54541 Hi Experts.
I have designed a buck converter with the below specifications.
Vin: 18V to 36V (Vin Nominal is 24V)
Vo: 12V at 5A.
I am using the same circuit as recommended by Webench. The only difference is, I have connected the…
Part Number: TPS54541
Problem
The output of my TPS54541 design is unstable regardless of load (I didn't push the load above 500 mA in fear of damaging the device)
Specifications
Vin = 24 V
Vout = 5V
Iout = 0 - 5 A

Part Number: TPS54541 The TPS54541 is supposed to allow 5V 5A output, but I found that following circuit limits the current output at 2.3A. Anyway can I adjust the current limit?
Part Number: TPS54541 Tool/software: WEBENCH® Design Tools In reaction to a customer request, I have created my own spreadsheet based on the datasheet for calculating the compensation of the TPS54541. The customer has particular parameters, but I decided…

Part Number: TPS54541 Hi We are planning to apply TPS54541. Is the over current protection function in the IC function? Is it set to 5A standard or can it be set separately?
The second is 150 ° C TJ Operating Range. I want to know that THERMAL SHUTDOWN operates…
