Part Number: TPS54334 Hi,
when we try to simulate TPS54334 in LTSPICE, we get error "Too few nodes ....", and I download spice model from TI own website.
My LTSPICE version is LTspice 17.1.15.0. When I search why that error arise from, I understand…
Part Number: TPS54334 Hi,
We are using a TPS54334DRCR and recently had a little more than 150 boards built using this part. Some of these units work as expected, some start in hiccup mode for a few seconds then start and some of them never go past that…
Part Number: TPS54334 Other Parts Discussed in Thread: TPS51396A , LM2727 , TPS51385 , TPS51386 Dear team,
The customer would like to use PGOOD signal as EN signal.The purpose of this concept is for shut down the device when output voltage is abnormal.
Is…
Part Number: TPS54334 Hi,
We are using the TPS54334 in our design and the output of the IC is defined for 3.3V. When i measure the output it is showing as 4.6V.
Below voltages are observed at the respective pins.
Input voltage 5V.
Enable pin voltage…
Part Number: TPS54334 I have a circuit that was built for the TPS54336ADDAR chip (first picture). Due to supply issues, the TPS54336ADDAR you see in the first picture was substituted with the TPS54334DDAR regulator by the CM. We are seeing a high failure…
Part Number: TPS54334 Hello, I trying to figure out what's wrong with 3.3V buck converter. It's use to power MCU and few interface IC's, so the load is not great, just about 100-300mA. Approximately 20-30% of broken boards have burned TPS54334 (short…
Part Number: TPS54334 Hello,
Is there an errata for PN: TPS54334DDA? I just wanted to know if there is a difference in form, fit, or function for the different die revisions?
Thanks
Part Number: TPS54334 Hi team,
My customer is evaluating TPS54334.
Is this part protected against a continuous short circuit on the output? The datasheet does not directly mention short-circuit protection, but the description of overcurrent protection…
Part Number: TPS54334 Hello,

One of these is signed for by Gdansk,…
Part Number: TPS54334 Hi Team,
As TPS54334 PGOOD is open drain structure inside the chip, so I suppose PGOOD can be left open if unused, am I right?
But customer still want double confirm from product line, as this device related to several new projects…
