I am working on an application which needs a dual power supply. The rest of circuitry is ready and while looking for a dual power supply IC, i came across LT3471. My application would need a +25v and -25v supply, with a current requirement of 100mA on each rail. I just want to confirm whether my judgement of this IC regarding the requirement is correct.
Parallelly, i will be simulating the circuit on LTSpice and check myself for any issues that might come en-route.
Looking forward to suggestions.
I have tried the simulation om LT Spice. I am getting the desired voltage levels but the time to settle is a bit too much. it is taking more than 25mSec to reach the desired voltage level on both the rails. Also the optional diode on negative voltage rail as shown in ev board schematic doesn't seem to work.
Is there any way the settling time can be reduced? I have attached a snip of schematic and simulation result. Looking forward to suggestions.
Depending too on how much output current is needed, you may also check dual output ADP5070 or ADP5071.
