Hi TI Team, We are using TPS65270 for one of our designs. Below are the specs: Vin= 7V Vout1 = 3.3V Iout1 = 1.5A Vout2 = 2.5V Iout2 = 0.5A The selected switching freq. is 625k as per the ref design, We have run the phase & cross-over freq…
Part Number: TPS65270 Hello Sir:
Please help to review our schematic.
Our output conditions shows below.
BUCK1: 3.3V/1A(max) for System
BUCK2 :9V/3A(max) for Charger
And the operation temperature is from 0 to 50 degree.
Please teach us how to calculate…
Part Number: TPS65270 Hello TI team,
My customer use TPS65270 output with motor driver load and sensor load, but motor driver will impact on sensor circuit.
so we want to konw how to aviod this or any PN better to replace. Thanks!
motor output: 5v/1A…
Part Number: TPS65270 If there any pin to pin OPEN / SHORT test result for TPS65270RGE, please let me know or attach these data on this thread.
Best regards,

On the start up timing of TPS65270, four cycle switching is stopped.
(These occur Buck1 side, Buck2 side is not occur stopped)
Please see waveform below;
①ch1 (Yellow): Vin (16V), ch2 (Blue): Vout (3.3V), ch3 (Red): Vsw, ch4 (Green…
Part Number: TPS65270 Is different VIN1 and VIN2 condition have any problem?
Example pattern is below;
・Difference voltage, VIN1: 5V and VIN2: 12V
・Either one, VIN1: 12V and VIN2: 0V
・VIN startup timing differ, voltage supply sequence of VIN1→VIN2…

I trying to simulation for TPS65270's loop compensation on Power Stage Designer, the Loop Calculator.
Please let me know about Gain information for TPS65270 below.
※Above entered spec is default value on Power Stage Designer…
Part Number: TPS65270 Datasheet P16 is described "fzff is smaller than soft start equivalent frequency (1 / Tss)".
When fzff is much higher than 1/Tss, is these condition possibility to occur high inrush current on startup?
I think that high…
Part Number: TPS65270 Hi team,
I got a question from customer.
Now connect LX1 / LX1 to 3.6V directly, and it can't output 5.5V, and the actual output is 4.5V.
That is to say, the output two voltages can exchange buck1 and buck2, and then it can't…
