Description
The ZCC1005Q is a high voltage, synchronous
step-down controller operates over a wide range input
voltage 9V to 100V. The ZCC1005Q delivers 5A
continuous load current with up to 96% efficiency.
The ZCC1005Q 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 ZCC1005Q exhibits
protection features that protect the load from faults like
under-voltage,over-current and over-temperature.
The ZCC1005Q is available in an QFN-20.

这是我们新开发的产品介绍：ZCC1005Q是一种高压、同步降压控制器，工作在一个大范围的输入电压9V到100V。ZCC1005Q提供5A连续负载电流，效率高达96%。ZCC1005Q采用固定频率峰值电流控制，内置补偿，消除了对外部组件的需要。高侧MOSFET的循环电流限制保护变频器处于过载状态。如果过电流状态持续的时间超过当前时间，则会触发打嗝模式保护。ZCC1005Q具有保护功能，可以保护负载免受欠压、过流和过温等故障的影响。ZCC1005Q有QFN-20版本
