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

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 !
