ＣＸ８８０１／１００Ｖ　Ｉｎｐｕｔ，１０Ａ　Ｏｕｔｐｕｔ，Ｓｙｎｃｈｒｏｎｏｕｓ　Ｓｔｅｐ－　ｄｏｗｎ　Ｃｏｎｖｅｒｔｅｒ

Description

The CX8801 is a high voltage, synchronous step-down controller operates over a wide range input

voltage 9V to 100V.

The CX8801 delivers 10A continuous load current with up to 96% efficiency.

The CX8801 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 CX8801 exhibits protection features that protect the load from faults like under-

voltage,over-current and over-temperature.
