Part Number: TPS54331 Other Parts Discussed in Thread: LM66100 Hi all, I have a setup with a TPS54331 configured to 5V output and want to OR between a primary(24V) and secondary (5V USB) power sources. The secondary 5V-usb source in only used during maintenance…
Part Number: TPS54331 Dears,
Customer use the TPS54331,the input is 24VDC,output is 5VDC.
1.Now they find when the C180 is 8200pF and C178 is 68pF and C172 is 22pF,the output waveform shows ladder,pls find attachfie for waveform#1.
2.When the C180…
Part Number: TPS54331 Hello,
In one of the applications, I am using TPS54331D which I need to step down to 5V from 12V and 24V based on the input voltage provided. The buck converter works fine in 12V input, but when I am increasing the voltage to 24…
Part Number: TPS54331 Hi,
We’ve had 4 instances now with our product in a particular geographical location whereby the 3.3V supply circuit has failed. On review of the failures, the catch diode has failed short and, in 3 units, the TPS54331 was also…
