MA5821 - 58V Asynchronous Buck Controller
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
