Part Number: TPS53355 Hi expert,
Customer used TPS53355 and see Vo has about 0.75V before turn on. Do you have any idea what might happened and how to prevent it?
Power on
Power off
Off state

Part Number: TPS53355 Hi,
My customer uses the TPS53355 under the conditions of Vin=12V and Vout=1.2V, Iout=0A. In one device, the output voltage became like the waveform in the attached document, and after a while, 1.2V was output normally. I'm thinking…

Attached is TPS53355 sch for 12Vin, 3.3Vo application.
We find that, during power off, there is wave on 12Vin, this may lead to Vreg rise, then controller begin switching and Vo start to increase…
Part Number: TPS53355 Other Parts Discussed in Thread: TPS53353 Hello,
Is there a comparison table for the specifications of TPS53353/TPS53355?
Thank you
Part Number: TPS53355 Hi Team,
The TPS53355 in the circuit is used under the following conditions: VIN=12V, Vout=1.03V, Iout max =20.4A.
And the design is as follows:
Note:
a. All capacitors in the above figure are ceramic
b. L1 has a DCR…
Part Number: TPS53355 What are the reel specifications when ordering the TPS53355DQPR? If one reel has 2,500 pieces, is the reel width W1(mm) 15.4[mm] or 12.4[mm]? The datasheet listed his two specifications for the TPS53355DQPR.

Hi Sir,
My customer design and MP TPS53355. However, there is FA for this MP product on the output voltage.
The designed output voltage is 5V. Abnormal case Vout is 0.9V. the fail…

Hello
I design the schematic according to the WEBENCH. But I find the output voltage is too large. The picture is waveform of output voltage. It seems that the large ripple iarises when high side MOS turns on. Is…
Part Number: TPS53355 Hi，engineer：
I had a problem debug&test the TPS5335 power supply，VIN=12V，Vout=2.5V，Fsw=500K
1、power on waveform is ok，at 5A load。
2、power on waveform have a ~2.1V voltage step，and then ramp to 2.5V，at 15A load。
3、power test…
