Part Number: TPS54225-Q1 Other Parts Discussed in Thread: TPS62902-Q1 , TPS54225 Hello, Looking for failure rate and failure modes information for the part number "TPS54225TPWPRQ1".
Thanks
Part Number: TPS54225
Dear team,
We test soft start waveform on our board. Based on datasheet description, device SS pin use 2uA charging Css.
But we find there is two step at SS pin. Could you let us know why there are two step at SS waveform?
Regards…
Part Number: TPS54225 Hi,
Our datasheet says PG pin should pull up to VREG5, with 20K - 150K ohm resistor, is there any risk if using 4.7K resistor, pull up to 4.7V?
Thanks.

Part Number: TPS54225 Hi expert,
Customer did TPS54225 short circuit test by push "short" on e-load and it's always SHORT. The ENABLE is controlled by CPLD. Once Vo drop, CPLD will disable ENABLE and then ENABLE again.
One thing from below…
Part Number: TPS54225-Q1 Hi Team,
We received inquiry from customer asking if there is a given equation to calculate the range of the expected current limit for a given inductor size? Because in datasheet (Electrical Characteristics = Current Limit) states…
Part Number: TPS54225 HI SIR
We use tps54225 to design 12v to 5.0V power supply, two problems are as follows 1. Is the OCP current limiting condition a valley current or a peak current? 2. When the OCP starts to enter the UVP, the IC enters the shutdown…
Part Number: TPS54225 Hi Sir,
My customer is using TPS54225 and they worry that VIN noise will affect the VCC, so they add a inductor to isolate them.
my question as below.
1, Is TPS54225 need to seperate the VIN/VCC?
2. If they separate them, I think…
Part Number: TPS54225 Dear TI Experts
I am now using TPS54225，12V to 5V,2A
When power on, the output voltage is 9V and then be pulled down immediately~
we have done many experiments： changed the Inductor 、add output Capacitance、use DC power supply， but…
Part Number: TPS54225 Other Parts Discussed in Thread: TPS54226 Hi, Could you tell me about TPS54225/TPS54226 EN pin pull-down resistor value? Customer wants pull-down resistor value information for circuit design. Also,Should the EN pin be pulled down externally…
Part Number: TPS54225 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Hi, Customers are considering TPS54225. Customer wants the HSPICE model for reference of consider. Is it possible for TI to provide not only the simulation…
