Part Number: TPS54428 Other Parts Discussed in Thread: TPS54427 , Have approved either TPS54427 or TPS54428 for this application. This circuit is working well for us for 5 years in production where the V_IN is a fixed 12VDC from another internal SMPS. In…
Part Number: TPS54428 Hi Team,
this is brandon.
we met a problem on tps54428 with small chance happening.
we could test the short between VIN-pin and GND-pin. but if we testing with the Multimeter resistance gear for several times, we could find that the…
Part Number: TPS54328 Hi team,
Customer would like to know what is the difference between TPS54328DRC and TPS54428DRC.
Except the current rating is 3A and 4A. Is there other different items needed to be aware of? They would like to do p2p replacement…
Part Number: TPS54428 Hi Team,
Would you advise my customer's inquiry that
When the TPS54428 is evaluated, the IC temperature and choke coil temperature at higher current load are NG.
I understand that the TPS54428 has a fixed IC with an OCP setting…
Part Number: TPS54428 Hi Team,
My customer found there is a drop in Vout while start up progress whatever the load is light or heavy. Can you help to clarify why the phenomenon happens?
Ps .
1 . The picture-1 is their .SCH
2. The picture…
Part Number: TPS54428 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!
Part Number: TPS54428 Hi, team.
My customer is now considering TPS54428.
The following question was received from the customer.
Can you tell me about this question?
<Question>
The recommended value of CBST is 0.1uF, but can you use it with 1.0uF…
Part Number: TPS54428 Hi all,
Im using TPS54428 in my device under mass production as a buck converter that converts 12 V to 5 V. However, when I made a mistake such as short circuit due mechanical touching or other reasons, my 5 V rail becomes short…
Part Number: TPS54428 Hello,
Due to MLCC shortage, customer want to use even higher value of C7, if allowed, C7=10uF.
Basically, huge capacitance takes more time of charging voltage for high-side switch, does this impact on minimum on time, which may…
