ZCC1001E  100V 1A降压芯片

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.
