PMIC similar to AS3722

Other Parts Discussed in Thread: TPS650861

Hello,

one of my customers is interested in Texas Instrument’s PMIC lineup. They're using an Nvidia TK1 GPU, but their PMIC solution (AS3722) is slightly “soft” radiation wise. They're looking to design a more robust power subsystem, using a small FPGA for control, a PMIC, and some external high current core/gpu supplies. Essentially, they want to replace the AS3722, but also design a flexible/generic power system to potentially power other SoCs/GPUs/FGPAs on space programs. Which PMICs would be best to recommend?

 Thanks,
Adam
