The TPS2490 manages the 12V payload power (PWR) and the TPS2331 manages the 3.3V management power (MP). Maximum power dissipation for an AMC is 60W, most of which will be supplied by the 12V payload power source. The PICMG.AMC specification requires both supplies to be inrush controlled and current limited.
