Part Number: TPS54531 Hi team,
Design with reference circuitry. The input is fixed at 24 V, the output is 7 V, the EN pin voltage is 5.5 V, and the load current is between 100 and 200 mA. There is now a probability (about one-thousandth) that the output…
Part Number: TPS54531 Hi,
For TPS54531DDAR new PCN add TI Mexico as an additional Assembly.
Is it have any marking change or how to define it before PCN or after PCN?
Thanks!

Part Number: TPS54531 Hello,
We are having sporadic startup issues with a design that implements a TPS54531, this design takes 5V to 3.3V with an average load of ~2A.
Cin = 9.4uF (x2 4.7uF in parallel) ; Css = 8.2nF ; Rcomp = 51.1k ; Ccomp = 820pF ; Ccomp2…
Part Number: TPS54531 I considering to calculate Cboot value and equation is below;
Cboot > (Qg + Icc × Duty/fsw) / ⊿Vc
・Qg:22.8nC
・Icc=110μA_typ
・fsw:570kHz_typ
My question: Is TPS54531 assume to set ⊿Vc voltage?
When ⊿Vc set less than 1V…
Part Number: USB-PD-CHG-EVM-01 Other Parts Discussed in Thread: TPS54531 Hello Sir:
Our application only used sink-only.
Can we change input voltage of TLV75533 from TPS54531 output to VBUS of Type C receptacle?
Does it has side effects?
And the other if…
Part Number: TPS54531 I simulating TPS54531 transient model on PSPICE for TI.
These model is described test only Vin: 8V to 28V, can this model use and simulation on 5Vin setting?
I try to set Vin:4.75V, Vout: 3.3V, Iout: ~5A simulation, changed points…
Part Number: TPS54531 Hi Teams,
Out of curiosity it would be nice to know how the UVLO resistors equations are derived.
And I saw there's a thread talking about this, my further question is why for Voltage created by 1uA& 4uA, resistors are calculated…
Part Number: TPS54531 Hello experts,
I have question for WEBENCH RθJA value amd power dissipation calculation. In WEBENCH simulation, RθJA is described as 40C/W, but datasheet shows 55C/W. Could you tell me where does WEBENCH value(40C/W) come from…
Part Number: TPS54531 Dear teachers:
About TPS54531, in the SPEC 8.3.3 ,i t says that the DCDC can operate at at 100% duty cycle as long as the BOOT-to-PH pin voltage is greater than 2.1 V Is this to say that if the VIN is 4V at the VOUT I can get a voltage…
Part Number: TPS54531 Hello,
I'm trying to convert 12v to 5V using TPS54531. To be safe, I use the same circuit as TPS54531 EVM but I'm not getting +5V output. I'm using a power supply bench to provide 12V input and I notice it goes directly to current…
