Typical Application

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.
