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.
