Description
The ZCC1001E is a high voltage, non-synchronous
step-down converter operates over a wide range
input voltage 9V to 100V. The ZCC1001E
integrates a 120-V 400-mΩ high-side MOSFET.
The ZCC1001E delivers 1A continuous load
current with up to 95% efficiency. The ZCC1001E
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 ZCC1001E exhibits protection features that
protect the load from faults like under-voltage,
over-current and over-temperature.
The ZCC1001E is available in an ESOP-8 package.
