Description
The ZCC1008B is a high voltage, synchronous step-down controller operates over a wide range input voltage 9V to 100V. The ZCC1008B delivers 10A continuous load current with up to 96% efficiency. The ZCC1008B 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 ZCC1008B exhibits protection feature that protect the load from faults like under-voltage,over-current and over-temperature. The ZCC1008B is available in an MSOP-10.
