Part Number: TPS2390 Hi ti team，
I am experiencing automatic shutdown of the MOSFET in my TPS2390 application. I cannot find out why it is shutting down automatically, but I have captured some waveforms that I would like technical support to analyze…
Part Number: LM5051 Other Parts Discussed in Thread: TPS2390 , Tool/software: Hello,
My customer is considering using OR-ing (LM5051) and Hotsawp(TPS2390/1).
They have a question about the use of MOSFETs in both devices.
Below are the application…
Hi Allan,
Sorry for the delay in getting back to you. The MOSFET with higher SOA needs to be selected. I have tried with maximum RSNS of 15 mΩ (minimum nominal current limit of 2.67 A), still the cell E94 is negative. CSD19536KTT might be an option…
Patrick,
TI has a number of hotswap ICs that will handle 12v/15A. The TPS24700/01, TPS24710/11, TPS24720 can do this and have EVMs build for 25A applications that are easily scaled as you need. Please see www.ti.com/hotswap for selection and design…
Part Number: TPS2399 Other Parts Discussed in Thread: TPS2398 Tool/software: Hi Team,
we use the CYStek_ MTE020N10RF3, but it always damage when we turn on and off power. and use IRF530_MOS can be pass, MTE020N10RF3_MOS always damage.

Hello,
The UCC3806 is a dual output controller though it can be used in a flyback where only one of the outputs are used to drive the switch it might be better to choose a single output controller. Look at page 46 of the attached under General Purpose…
Siyu,
I think the toggle flip-flop in the block diagram on page one of the spec should have let you know that the max you will get with this device is 50% duty.
Go to page 43 and 44 of the attached and select a more suitable part.
Peter,
i am enclosing the Power Management Guide for 2011. The section you will be interested in starts on page 43 and actual devices listed on page 46, With the minimum information you have given me I would expect that you will want something like…
Hi,
I've attached the 2013 User's Guide for power products. Starting on page 53 you will find a selection of PWM controllers. many of these teh frequency can be varied according to external criteria.
As an example if you use a UC3842 it is a simple…
