The MP1471A 3A 16V 500kHz is a high-frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs on the Whatsminer H3 control board. It achieves 3A output current over a wide input supply range with excellent load and line regulation. The MP1471A features synchronous mode operation for higher efficiency over the output current load range. Current mode operation provides a fast transient response and simplifies loop stabilization. Protection features include overcurrent protection and thermal shutdown.
