Description

The ZCC1001E is a high voltage, non-synchronous  step-down converter operates over a wide range  input voltage 9V to 100V. The ZCC1001E  integrates a 120-V 400-mΩ high-side MOSFET. The ZCC1001E delivers 1A continuous load  current with up to 95% efficiency. The ZCC1001E  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 overcurrent condition has persisted for longer than the  present time. The ZCC1001E exhibits protection features that  protect the load from faults like under-voltage, over-current and over-temperature. The ZCC1001E is available in an ESOP-8 package.
