Part Number: TPS54429 Tool/software: Hello
I set the Vout of the TPS54429 to 0.95V and shorted Vout to GND.
The results are in the attached document.
Green is Vout and yellow is Iout.
Even when Vout is shorted, it is not 0V but remains at about 120mV…
Part Number: TPS54429 Tool/software: Hello teams
From the datasheet it has below comment.
The TPS54429 is a 4.5-A synchronous step-down (buck) converter with two integrated N-channel MOSFETs. But electronical specification tell that current limit is defined…
Part Number: TPS54429 Tool/software: Hello teams
The recommended Vout for the TPS54429 is 5.5V,
but if it is set to 5.66V, what kind of abnormal behavior will occur in the TPS54429?
The absolute maximum rating is 6.5V, so I understand that the TPS54429…
Part Number: TPS54429 Other Parts Discussed in Thread: TPS54425 Tool/software: Hi team,
As my customer's system modifies the input voltage from 12V to 5V, they are looking fore TPS54429PWPR P2P alternative which supports 5V input.
It looks like TPS54425PWPR…
Part Number: TPS54425 Other Parts Discussed in Thread: TPS54429 , Hello teams
But it's output ramp up only til 4V on our design. And Both Vout level is decreasing gradually until around 3.5V. As you can see in our schematic, it's behavior would happen…
Part Number: TPS54429 Dear team,
Could you help to confirm VIH of EN pin?
In device datasheet, the minimum of VIH is 2V. But we test on our board, device is enable once EN voltage level higher than 0.77V.
And I find an E2E post, the EN threshold is around…
Part Number: TPS54429 Dear team,
I check with datasheet and there are no latch protection for TPS54429.
We do power on/off cycle testing for TPS54429, but output voltage does not present even Vin back to12V. We have to remove input power and wait input…
Part Number: TPS54429 Hi,
I would like to ask you about the TPS54429 device. The formula for calculating the frequency Fp with L1 and C8 + C9 of Output Filter Selection is described in the data sheet. Please tell me how to think about the design target…
