MA5821 58V Asynchronous Buck Controller ā– GENERAL DESCRIPTION The MA5821 is an asynchronous buck controller. The device needs external high side power MOSFET and low side schottky diode, and provides 3A of continuous load current over a wide input voltage of 10V to 58V range. Current mode control provides fast transient response and cycle-bicycle current limit. An internal soft-start function prevents inrush current at turn-on. This device is available in small MSOP-10L-EP package, and provides a very compact solution with minimal external components. ā– FEATURES - Wide 10V~ 58V Operating Input Range - External High-Side P-channel MOSFET Switch - Output Adjustable : VFB(1.
