일반 설명
The ET8A50QA is a high voltage, synchronous step-down controller operates over a wide range input voltage 9V to 100V. The ET8A50QA delivers 5A continuous load current with up to 96% efficiency. The ET8A50QA 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 ET8A50QA exhibits protection features that protect the load from faults like under-voltage,over-current and over-temperature. The ET8A50QA is available in an QFN20.
