Overview of 100V wide input DC-DC specifications:

• CX8801 is a 9V to 100V high-voltage synchronous step-down controller that can operate in a wide input range of 9V to 100V.

• CX8801 provides a continuous load current of 10A, with an efficiency of up to 96%.

• CX8801 adopts fixed frequency peak current control with built-in compensation function, and does not require external components.

• The cycle by cycle current limitation of high-end MOSFETs can protect the converter in case of overload.

• If the duration of the overcurrent condition exceeds the current time, it will trigger the burp mode protection.

• CX8801 has a protection function that can protect the load from faults such as undervoltage, overcurrent, and overheating.
