100V 输入同步降压最大5A输出电流 ZCC1005                             

Description

The ZCC1005 is a high voltage, 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.
