RY8630 Description/描述：
The RY8630 is a current mode monolithic buck switching regulator. Operating with an input range of 4.5V~60V, it supplies 3A of continuous output current over a wide input-supply range with excellent load and line regulation. At light loads, the regulator operates in low frequency to maintain high efficiency and low output ripple. Current mode control provides tight load transient response. RY8630 achieves low EMI signature with well-controlled switching edges. Fault condition protection includes programmable output-voltage Protection, detectable output short protection, thermal shutdown and input under voltage lockout. The RY8630 is available in ESOP8A, ESOP8B and ESOP8C packages, which provide a compact solution with minimal external components.
RY8630是一个电流模式的单片降压开关调节器。它的输入范围为4.5V~60V，在较宽的输入-供电范围内提供3A的连续输出电流，具有良好的负载和线路调节。在轻负荷下，调节器在低频下工作，以保持高效率和低输出纹波。电流模式控制提供了紧密的负载瞬态响应。RY8630通过控制良好的开关边缘实现了较低的EMI签名。故障状态保护包括可编程输出电压保护、可检测输出短路保护、热停机和电压锁定下的输入。RY8630有ESOP8A、ESOP8B和ESOP8C软件包，它们提供了一个具有最小的外部组件的紧凑解决方案。
