MA5821-58V Asynchronous Buck Controller DataSheet

GENERAL DESCRIPTION
  The MA5821is an asynchronous buck controller.The device need externals high side and
external highside power MOSFETs, andprovide 3A of continuous load current
over a wide input voltage of10V to58V. Current mode controlprovides
fast transient response and cycle-bicyclecurrent limit.
An internal soft-start prevents inrush current at turn-on,
this device available in small MSOP-10L-EP packages,
provides a very compact solution with minimal external components.
