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 over current 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.
