Part Number: TPS3124 Other Parts Discussed in Thread: TPS35 ,
Dear team,
I have doubt with start up delay functionality. As per datasheet, on page no. 19, it is mentioned, "The tSD frame is not initiated when the watchdog functionality is enabled…
The nRESET assertion time requires 25 us for a reset caused by voltage at VDD. The WDI pin recognizes pulse with width greater than 100 ns. This should give you the timing required to estimate the sensitivity at the moment reset is asserting and a watchdog…
Unfortunately, there is not way to guarantee the TPS3824 watchdog timer will not time out at 0.9s. There is not anything you can do to the IC to modify this built in timing. There are several other SVS products with watchdog timers that have different…
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.

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…
Gary,
Most any of our power controllers with dual output capability will provide the control. See attached document starting at page 50 with the dual output controllers on page 53 and 54 and choose what features you want.
Regards,
John
