MST MST8820A1KP

The MST8820AXKP is a high voltage, Asynchronous step - down converter operates over a wide range input voltage 9V to 80V. The MST8820AXKP integrates a 100 - V 400 - mΩ high - side MOSFET. The MST8820AXKP delivers 2A continuous load current with up to 93% efficiency. The MST8820AXKP operates with fixed frequency peak current control with built - in compensation eliminates the need for external components. Cycle - by - cycle current limit in high - side MOSFET protects the converter in an overload condition. Hiccup mode protection is triggered if the over - current condition has persisted for longer than the present time. The MST8820AXKP exhibits protection features that protect the load from faults like under voltage, over - current and over - temperature. The MST8820AXKP is available in an ESOP - 8 package.
