Features l 9V to 100V input voltage range l 10A continuous output current l 96% Peak Efficiency l 500µA operating quiescent current l Peak Current mode control l 150 kHz Fixed Frequency l Internal compensation for ease of use l Up to 91% duty cycle l 0.8V voltage reference l 9µA shutdown current l 150ms Hiccup mode short circuit protection Function l Thermal shutdown Function l MSOP-10 package 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.
