I am following www.analog.com/.../8471fd.pdf this datasheet (Figure 10a) to develop a +-12V from 24V Supply. Is there any calculation sheet available that can be shared, that will help me choose the passive elements.
figure 10a in the datasheet on page 30 shows an example which fits your basic requirement. I'm not aware if a tool is available, so you have to work with the formula given in the datasheet to calculate any changes which you would need to the given example. You should use LTSpice for a check on your calculated externals and see if they perform as desired/intended bwfoe real hardware is tested
For Jeronym: The LT8335 won't fit for a 24 to +-12V application as the internal switch has a too low voltage rating of 28V for the mentioned application. The power switch will see at least the sum of VIn and VOUT.
Thank you foe pointing me out.
Would you please explain more about that SEPIC dual +- output? In this circuit of LT8335, can I replace L1B and L1C with 2 Schottly diodes? Just like the circuit of LT1930 in the datasheet on the end of page 8.
to emphasize the purpose of this forum: It's intended for help when/for using our components. We cannot teach switch mode power supply or analog electronics in general. Hence I would recommend following:
1. Look for some good books resp. AppNotes dealing more in general with the topic (AN19 or 30 for example):
2. If you want to know more about circuit behaviour you have our LTSpice tool to check every voltage and current in the circuit with transient simulations (and other simulation types as well). It's quite easy and you will have the mentioned LT1930 schematic in 10-20 minutes implemented.
Have fun and enjoy the topic!
I am studying how to handle LTSpice and other tools.
And I used to use Multisim to run. Since a app often combines IC from other corp. Can you offer some documents or notes about guide of insert ADI IC model to Multisim?
