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.
