Part Number: TPS62148 Hi,
The output voltage rises up to the input voltage by the back electromotive force which is generated when the dc motor which is the output load for TPS62148 is suddenly turned off with the forced PWM mode. At this time, the FB…
Part Number: TPS62148 Other Parts Discussed in Thread: TPS563208 Hi team
I want to know switching frequency vs input voltage is change depended on output voltage like TPS563208 (datasheet p7, figure7) or not.
If there is some data please share with us…
Part Number: TPS62148 Hi Team,
One quick question.
What is the status of the PG output when EN is set to low (device disable condition)?
Regards,

We are currently using the TPS62148 in our design and we are trying to keep as much as possible of the corresponding Evaluation Module layout. The layout is documented in TI TPS62148 Evaluation Module User's Guide (SLVUBE9) and…
Part Number: TPS62148 Hello,
Would you kindly provide feedback on customer questions below:
(1) The data sheet states RθjA: 38.4 ℃. Under what conditions is this the value?
Since there was a link to SPRA953C in the data sheet, I presumed that it…
Part Number: TPS62148 I was hoping for some help regarding the 100% duty-cycle operation of the TPS62148 for 5V output.
1) Figure 80 from the DS shows around 700kHz switching frequency before the graph ceases (device enters 100% duty-cycle mode?) - This…
Part Number: TPS62148 Other Parts Discussed in Thread: TPS62480 Hello experts,
I got question about layout from customer.
My customer want to move vias from datasheet recommendation as below.
In this case, we need to move C1/L1 due to vias location. Is…
Part Number: TPS62147 Other Parts Discussed in Thread: TPS62135 Team,
-Is it possible to use a TPS62147RGXR / TPS62148RGXR on an existing TPS62135RGXR PCB? All 3 devices have the same VQFN-HR package. The main difference is pin 4 (FB2 on x35 and AGND on…
Part Number: TPS62148 Hello experts,
I got question about GND solid pattern under inductor from customer. Could you give me advice?
In generally, it is better to remove GND solid pattern under inductor because it may cause noise influence (e.g. eddy…
Part Number: TPS62148 I need to support a customer design with TPS62148. 12Vin to 5V / 3.3V out, at 400mA max load.
The customer has done the design before with PWM mode, but really needs squeeze the highest performance possible out of the device for…
