Part Number: TPS54821 Hello,
I would like to use TPS54821 IC to generate -3V from 6 V for a kind of high current (5-6A) max 8A application.
For this purpose I have already ordered TPS54821-EVM-0049. I would like to check with this EVM that -3V is doable…
Part Number: TPS54821 Hello,
We are thinking to use relay for TPS54821’s Vin on/off.
Is TPS54821 broken if frequently power on/off?
We are need to “Slow-start” function, so for that frequently
Vin on/off Is required.
I will show you…
Part Number: TPS54821 Hello,
In my design I use TPS54821 to convert from 12V to 8V.
Unfortunately the output voltage not stable around 2V instead 8V
Thanks

Hi Team:
here attach the customer test summary. can you help to check why the SW will disconnect under 1000Mhz in light load like 0.7A?
tks !

Part Number: TPS54821 Other Parts Discussed in Thread: LP5912 , TPS74801 Hi ti team,
I need to control the EN pin of TPS54821 by one GPIO of MCU. Before I read 7.4.1 for Enable control, I am going to pull down the EN pin by a resister to keep TPS54821 off…
Part Number: TPS54821 Hi expert,
Customer used TPS54821 with 12Vin to 3.3Vout. The ENABLE pin seems can leave floating or pull up to 12Vin or make a R divider to enable the device. Which way can boot up the device to 3.3Vout in the quickest way?

Hi, Support Team
Please help recommend a power switch which can meet Vin max 15V, continue current 6A. TPS54821 can meet spec?
our customer spec:
normal Vin=12V; Vout:12V / Iout…
Part Number: TPS54821 Hi,
Mu customer have TPS54821 vout drop issue.
Please see below waveform.
CH1: Iout
CH2: Vout
CH3: SW
But when Iout increase, Vout drop to 1.324V. And trig PWRGD low threshold.
we also check inductor should be meet spec.
Below is…
