Part Number: TPS650250 Hi team,
Could you please let me know about unused Vdd_alive (VLDO3) termination for TPS650250?
- Is it OK to leave it floating?
- Is the recommended output cap (2.2uF) needed?
- Is the load resistor needed?
Best regards,
Itoh
Part Number: TPS650250 Other Parts Discussed in Thread: AM3352 Hi，
We use AM3352 and PMIC TPS650250 a s a design.
How to guarantee the power supply performance without PI simulation?
Is there any guides or tools we can use for power integrity design.
Thank…
Part Number: TPS650250 Hi,
My customer tries to use TPS650250 by replacing from multiple power ICs.
They only use Vout:3.3V, 2.5V, 1.2V by DCDC1, DCDC2 and DCDC3.
Thus, they don’ t use LDO1 and LDO2.
In this situation,
Could you answer how they…

We are using TPS650250 to power C6746 DSP, however, as one DCDC is used to power Flash, when load becomes heavy, the output voltage will…
Part Number: TPS650250 Hi,
I am using TPS650250 in my design.
1. Can you please let me know how to calculate the power dissipation for PMIC.
2. What is the efficiency for DCDC1 for VI=5V and Vout=1V
3. What is the efficiency of DCDC3 for VI=5V and Vout…
Part Number: TPS650250 Hi Sir
The customer uses VINDCDC1 to input 5V and output 3.3V. When the EN pin is logic lowered, there is still output at 3.3V. May I ask why?
we change another IC in this board ,this phenomenon still excit .

Part Number: TPS650250 Hello guys,
One of my customers is considering using TPS650250 for their new products.
They will use DCDC1 of the device for ARM CPU core as 1.26V power supply set by 2 external resisters (1.1k ohm - high side and 910ohm - low side…

Hi,
I am using TPS650250 to power my ARTIX-7 FPGA XC7A50T-2CPG236C.
Attached is the power tree used. And power estimation of ARTIX-7
As per xilinx datasheet minimum ramp time for all power rails should be 0.2ms. Can you please…
