Part Number: TPS22949 Does the V+ pin on the TPS22949 play any role for the current limiter portion of the chip? I ask because I will not be using the LDO feature and setting EN2 as a low. According to the block diagram on figure 42, it shows V+ going…
Part Number: TPS22960 Other Parts Discussed in Thread: TPS22949 Hi, TPS22960 is unavailable worldwide in any package. We need an alternate 2-switch device in a similar overall package size to TPS22960DCNR, with industrial temp ratings. The design doesn…
Hi Sharma,
In addition to Clemens comments, you may consider the instrumentation amplifier, INA333 was very popular in that application, but we have tons of instrumentation to choose from.

Hi Ashwin,
What is the max and min input signal to the preamplifier? Is this single power supply or split power supply?

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…
Keivan,
Using two 1M resistors instead of 2.8k shown in INA128 datasheet sets the gain of INA128 to G=1.025, and thus as you said minimizes amplification of the signal1, but this is a wrong signal since INA128 amplifies differential and not common-mode…
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…
