Hi Enrico,

These are some option for dual-output POS and NEG supply. This depends on your input voltage source. 1A is kind of large for the NEG output.

Hi ARad,

Thank you for the detailed explanation above. Can you provide guidance for acceptable accuracy at lower ranges of VCTRL1? One such operating point is:

• VCTRL1 = 0.3V
• Vout = 2.6 V
• Iout = 5 A

In general we are looking to drive a commanded constant…

Hi Otmar,

You may want to check these better options for your need: single part that can do POS and NEG outputs. ADP5071, ADP5071, ADP5076, LT3471

Hi Fil,

I did use the bxl file from the ADI website, then uploaded it to the Ultra Librarian website.

It was for parts LT3471, LT8471 and ADM7150.

I've worked it out, they are IPC Least, Normal and Maximum footprints.

It didn't happen with bxl files…

Thank you for your reply ! 

It looks like both  ADP5071, LT3471 will not give me as much power as the LT8582

Please check ADP5071 and use the design tool that can be downloaded from analog.com

Or a similar part LT3471.

Hi Niuton

The 2A is the inductor peak current. Output current is lower. You need to find out how much total current will be pulled by your load on both +15V and -15V outputs.

Please look at better products ADP5070/71/72, LT3471 that can produce dual POS…

Check out LT3471 and LT8582.

I was looking at that one too in addition to the LT8471. 2 LT8580s just looked to be less complex at first glance. Maybe not. PCB area-wise maybe the LT3471? Although it would be nice if it could handle up to 18V input voltage. 

首先LT3471是linear的产品，不是ADI的……

其次，LT3471也会有环路稳定问题，需要测波特图分析。

开关电源电流路径中，电流检测点在电压前边，所以在电压变化之前就会被检测到，所以比电压环路补偿要快。
