    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是一個電流模式的單片降壓開關調節(jié)器。它的輸入范圍為4.5V~60V，在較寬的輸入-供電范圍內提供3A的連續(xù)輸出電流，具有良好的負載和線路調節(jié)。在輕負荷下，調節(jié)器在低頻下工作，以保持高效率和低輸出紋波。電流模式控制提供了緊密的負載瞬態(tài)響應。RY8630通過控制良好的開關邊緣實現了較低的EMI簽名。故障狀態(tài)保護包括可編程輸出電壓保護、可檢測輸出短路保護、熱停機和電壓鎖定下的輸入。RY8630有ESOP8A、ESOP8B和ESOP8C軟件包，它們提供了一個具有最小的外部組件的緊湊解決方案。
