Description
The ZCC1005 is a high voltage, non-synchronous
step-down converter operates over a wide range
input voltage
9V to 100V. The ZCC1005
integrates a 100-V 400-mΩ high-side MOSFET.
The ZCC1005 delivers 1.5A continuous load
current with up to 95% efficiency. The ZCC1005
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 ZCC1005 exhibits protection features that
protect the load from faults like under-voltage,
over-current and over-temperature.
The ZCC1005 is available in an ESOP-8 package.
