Allen,
The TPS54283 datasheet has design procedures and examples. I would follow the design procedure for each of your outputs. I would start with the fixed output supply first, as it is easier. When you do the adjustable start with using the lowest…
There is a power quick search at power.ti.com that can help you find suitable devices. If you could reduce your Vin range, the TPS54283 or TPS54383 would be great fits. Otherwise, the TPS54240 suits your specs.
Other Parts Discussed in Thread: TMS570LS3137 Dear all,
TI ARM guru Zhaohong has provided the HDK schematics (tms570ls3137) within this thread .
On my desk I have a board with the revision number - PCB 4197281 REV D. According the circuit lines in…
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
