Part Number: TPS2049 Hi Team,
I have a question about the OC pin output of the TPS2049.
Is it correct to understand that when the overcurrent protection is activated, the OC output goes to L level? (It is H level during normal operation.)
From…
Part Number: TPS2049 Tool/software: Hi Team,
If the overcurrent protection function is activated and the voltage drops,
causing the current to become smaller and fall below the overcurrent threshold,
will the overcurrent protection function be…
Other Parts Discussed in Thread: TPS2049 , TPS2552 Please let me know about TPS2049 current limit operation. TPS2049 has IOS(100mA to 200mA) characteristic and IOC_trip(max 325mA). What is these difference? Is the output current limited to IOS value by…
Other Parts Discussed in Thread: TPS2061 Is it necessary to have an electrolytic on the output? The output of the TPS2061 will power a radio with a 700mA transmit current rating. Can a 22 uF ceramic be used instead of a electrolytic?
Hi Guy Yater,
Thanks for the response.
When I was going through http://www.ti.com/lit/sg/sszb130b/sszb130b.pdf this document & I found recommended part as TPD8E003.
So now I'm in confusion to use any one of them, Can you please suggest me , which…
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…
