Description
The ZCC1005Qis a high voltage, synchronous step-down controller operates over a wide range input voltage 9V to 100V. The ZCC1005Qdelivers 5A continuous load current with up to 96% efficiency.
The ZCC1005Qoperates 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 ZCC1005Qexhibits
protection features that protect the load from faults like under-voltage,over-current and over-temperature. The ZCC1005Qis available in an QFN-20.
