If I use the LT8582 in a similar configuration as the design "1.5MHz, 5V to ±12V Boost and Inverting Converter" as shown in the data sheets but I change the output to +/- 13V what will be the effect ?
The converter should work very much the same, except it will deliver a little less load current, since the output voltage is higher.
How much can I expect the Max load current where I can find this information or calculation in the data sheet ?
Also can I keep all of the components (except for the voltage divider) the same ?
The two outputs are not symmetrical. The positive output has more capability than the negative, and 14.4 watts is the max recommended output power for +/-12V outputs.
That power level would not increase if the outputs go from 12V to 13V.
No, I do not have a suggested single part for your application. The part I suggested, LT8364 was my best suggestion.
And, the 5% was based on a rough calculation I made based on higher duty cycle needed.
Thank you fro your reply.
Is there some way I could adjust this design to make the current supplies (for +/- 13V) symmetrical ?
This dual converter cannot be guaranteed to deliver 700mA per output (with a 5V input). If you decrease your load currents or increase the input source, this converter might work for you.
An input voltage of about 8V would you 700mA per output.
If I wanted to get higher output voltages e.g closer to +/-20V what type of input voltages should I supply ?
Please follow guidance on page 15 for the negative converter, and page 13 for the positive.
