Part Number: TPS54329 Dear Team,
There were abnormalities in three samples produced by the customer. The EN pin was normally high, but the output was only 1.2V. Later, after replacing U5 TPS54329, all three units were normal and the output voltage…
Part Number: TPS54329 Dear Team,
Below is the circuit we used for the 3.3V power rail. Concerning the soft-start time, we modified CB39 from 3300pF to 470pF as part of power sequence optimization. However, after this change, several units failed to…
Part Number: TPS54329 Dear team,
We are testing OCP function of TPS54329 and find PWM is still there once current limit be trigger.
But output voltage drop to zero during OCP.
According to datasheet, device will turn on low-side FET until no over…
Part Number: TPS54329 We use tps54329 to output 5V voltage, but when testing the power on waveform, we find that there is a return channel. Excuse me, how can we solve this problem? The design drawing is as follows:
Part Number: TPS54329 Other Parts Discussed in Thread: TPS54239 , TPS54339 , TPS54327 , , TPS54328 Hi Sir,
My customer would like to use TPS54329DDAR to replace TPS54339DDAR since the device shortage.
TPS54239 is an older device than TPS5433, right…
Part Number: TPS54329 Use TPS54329 to realize 12V to 3.3V 。Select the C20 68 pF, the phase margin of test is best. But the datasheet of TPS54329 on Page 13 descripts the capacitor is 5~22 pF。Can I choose 68 pF？
The Phase Margin Test Result…

Hi,
My customer is testing TPS54329 to replace BD9329AEFJ.
The schematic is as below: the parameters are commented in the red box. Input is 12V, output is 5V,2W.
They device can't work at -35C temperature.
But the device…
Part Number: TPS54329 Team,
Customer is using TPS54329 in their system, and powering it up with 12V. They would like to improve efficiency, and ease the layout by using 3.3V or 5V Vin, however datasheet says >4.5V is needed, and customer's experience…
Part Number: TPS54329 Hi
because the MOSFET are in the converter, the spec only show the SW(low side MOSFET) max voltage=22V.
We want to know the high side MOSFET max voltage=?
Thank you!
