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 would recommend you use separate converters for your application. If your input voltage is 5V or more, the LT3471 will require special care with soft-start. That is in order to ensure the switch is not subjected to simultaneous high voltage and current during startup. Please refer to the last section of the Soft-Start paragraph on page 7.
The LT3580 would be a much better part for your application, but yes, it would require two separate parts.
Depending on your input voltage range there might be other options, better suited for your application.
