+15V and -15V output current almost 3A

DC-DC Power Converters

Hello, I am looking for a Power ASIC solution that can output +15V and -15V. The current must reach about 3A, so it is impossible to use the internal MOSFET to drive the power inductor. It doesn’t have to be a single ASIC dual-channel output; I can accept the solution of two. Please give me some advice on how to choose the most suitable solution, thank you very much !

Sincerely.
Abraham

Hi Abraham,

What is your required input voltage?

You could try making an inverting-buck boost using our MPM3530 | 55V 3A Step-Down Power Module | MPS (monolithicpower.com). This part can support +/-15V 3A output.
