Part Number: TPS54240 Other Parts Discussed in Thread: LMR51420 , LMR51430 Dears,
Customer feedback that the Continuous current diode during the end customer use process,pls help to check the schematic whether have any problem or not?
Part Number: TPS54240 Other Parts Discussed in Thread: TPS54340B
Please let me confirm two points below about synchronizing to system clock.
①Is below schematic no problem?
Clock source is 3.3V CMOS output (Logic IC), it is not Hi-Z.
Clock source is…
Hi Richard, My apologies for the delay. Your response really helped a lot. However, our customer can't change the compensation network circuit because the production is active and the components were already bought. Could you help us analyze whether their…
Part Number: TPS54240 Other Parts Discussed in Thread: TPS54140 , Team,
Is the criterion of skipping mode between TPS54140 and TPS54240 the same? Or they're not the same?
Since system requirement in customer side, the original TPS54140 is changed to…
Part Number: TPS54240 Hello,
I am designing a power supply with a TPS54240QDGQRQ1 buck converter that reduce from 12V to 5V and load from 500mA to 2A.
Unfortunatelly this is old design and I have to keep some part fixed until I have option to change.…
Part Number: TPS54240 Hello guys,
One of my customers is evaluating TPS54240 for their new products.
They use parts parameters which calculated by TPS54240 Webench.
Their Vin/Vo/Io conditions are the follows.
Vin = 33.2V(Min), 36.9V(Nom), 40.6V(Max)
Part Number: TPS54240 Hi Expert,
I have an question about the negative voltage on SW node.
I have checked the following E2E session and application note.
Part Number: TPS54240 We have a customer problem where the EN pin on the TPS54240 could be biased > 5V, but at very low current going into the EN pin. This problem is limited to the first run of boards and the design will be corrected ASAP.
Part Number: TPS54240 Other Parts Discussed in Thread: TPS54260 Hi Team,
My customer using TPS54240DGQR but now they need Vin:7 – 40 VDC, Vout:11.5 VDC Iout:Min. 0.5 A.
When i search package group HVSSOP(DGQ) 10pin i can not find any pin to pin alternative…
Part Number: TPS54240 We have successfully used TPS54240 on many circuits where we had higher input voltages such as 12 Volts and above. We are for the first time using this part with 5V input and we see that it is not regulating to 3.8V output. When the…
