The ZCC1005Q delivers 5A continuous load current with up to 96% efficiency. The ZCC1005Q 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 ZCC1005Q exhibits protection features that protect the load from faults like under-voltage,over-current and over-temperature. The ZCC1005Q is available in an QFN-20.
