Part Number: TPS65560
I would to get your opinion on which Controller, D/A Converter, or Analog Circuit would be best suited for use with the TPS65560. I will be using a 12VDC 3A wall wort as a power supply.
Hello Joseph, would you please clarify what you are looking for?I think you are referring to the diagram in the datasheet shown below.
The TPS65560EVM-165 page 7 shows "Analog Circuit" implementation for setting Ipeak and controlling CHG and F_ON.
There a many A-D converters that could be used to set the Ipeak levels.It is relatively easy to program the peak current at the primary side. The peak current can be set from I(PEAK1) to I(PEAK2) by using the I_PEAK pin of the TPS65560/TPS65561 (see Figure 9 in the datasheet). These values (I (PEAK1) and I (PEAK2)) are specified in each product data sheet. Section 2.1.3 discusses this in detail.As there are many uP or uControllers that can drive the whole system that uses an LED flash.Many uControllers have A-D's and GPIO that will allow use with an LED flash.
Portable device applications, such as digital still cameras (DSCs), digital video cameras (DVCs), optical film cameras, mobile camera phones, and PDAs with cameras, will have a processor or 2 that would be utilized to control the TPS65560 LED flash.
The control must:1. tell the flash it is time to charge because a Flash is imminent.2. Adjust the Ipeak, referenced in 2.1.3 of the datasheet.3. Trigger the flash to happen
The simple control of the TPS65560 enables it to be used in a wide range of processor based, or non processor based, designs.
Are you able to share more details of how this would be used in your system?

In reply to EdWalker:
Thank you for all of your input. I have ordered a TSP65560EVM-165 module which should arrive shortly. After a lot of study on my part, you are absolutely correct that this should do the trick. The down side is that I will have to bother you with some very mundane questions which I hope you have time for.
In reply to Rittter:
Joe you will not bother me or us (TI) with further questions.If you have a question, ask it on the TI Forum.
I will close this thread out now, it seems complete.
Please use the Forum and remember to ENTER A PART NUMBER when you post.This provides proper routing within TI to the product owners.
Have a great day and 73's. (KG5SUZ)
