Here is a schematic of the 1.8V supply circuit. Vin is 8.0V (labelled 12V) and is stable long before the Enable input goes hi. The 1.8V PG output is wired to the PG output of a 2.5V supply, also a TPS54226. The 2.5V supply comes up several milliseconds…
Other Parts Discussed in Thread: TPS54326 , TPS54226 Hi Team,
Our customer would like to compare the efficiency of TPS54226 with TPS54326.
Therefore, they simulated it on a condition as follows.
[condition]
-Vin=7.6V to 8.4V
-Vout=0.9V …

Hi Team,
Our customer would like to use TPS54226 or TPS54326 at the following condition.
Therefore, They would like to know the efficiency of the each…
Other Parts Discussed in Thread: TPS54226 , TPS54426 Hi,
If Enable is Low, is VREG5 of TPS54226 not active?
" VREG5 is not active when EN is low" is described to datasheet of TPS54426
(please refer to page5 of datasheet)
But, it isn’t described…
Other Parts Discussed in Thread: TPS54226 My customer is thinking they use TPS54226 on attached circuit condition.
They want to make output ripple level lower. So they increase inductor value to 10uH.
This value isn't in recommend component value…
Other Parts Discussed in Thread: TPS54226 Hi,
Our customer would like to use TPS54226 on the following condition.
Can they separate VCC from VIN?
I think that it is usable for the recommended voltage range*.
Could you please give us your advice…
Other Parts Discussed in Thread: TPS54226 , TPS54526 Hello,
My customer want a layout design of QFN package of TPS54226.
There was only the layout design of HTSSOP to the data sheet.
If there are a layout design and guidelines on QFN package,…
Other Parts Discussed in Thread: TPS54326 , TPS54226 Hi Team,
Our customer are going to use TPS54226 or TPS54326 at the following conditions.
Vout=1.1V @ Vin=7.6V , Iout=700mA
Vout=1.4V @ Vin=7.6V , Iout=200mA
They would like to know the actual…
Other Parts Discussed in Thread: TPS54226 I would like to use the TPS54226 in parallel with a linear regulator. The linear would be operational when the 54226 is in shutdown mode, so there would 3.3 V present on VOUT when the device is in shutdown mode…
Hi,
We confirmed the following conditions with the TPS54226EVM.
(Could you please refer to the attached file.)
[conditions]
Case1 : VEN = 0V at VIN=5.0V , VCC=0V , EN=Hi-Z
Case2 : VEN = about 280mV at VIN=0V , VCC=5.0V , EN=Hi-Z
Case3…
