一.产品概述
The CXDC6577 is a monolithic step-down switch mode converter with a programmable output current limit. It achieves 2.5A continuous output current over a wide input supply range with excellent load and line regulation.
The maximum output current can be programmed by sensing current through an accurate sense resistor.
It can output constant current and voltage. Internal thermal shutdown, cycle-by-cycle current limit protection.
The CXDC6577 requires a minimum number of readily available standard external components. The CXDC6577 is available in 8-pin SOIC8-EP packages.
