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是一個(gè)電流模式的單片降壓開(kāi)關(guān)調(diào)節(jié)器。它的輸入范圍為4.5V~60V，在較寬的輸入-供電范圍內(nèi)提供3A的連續(xù)輸出電流，具有良好的負(fù)載和線路調(diào)節(jié)。在輕負(fù)荷下，調(diào)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(fù)載瞬態(tài)響應(yīng)。RY8630通過(guò)控制良好的開(kāi)關(guān)邊緣實(shí)現(xiàn)了較低的EMI簽名。故障狀態(tài)保護(hù)包括可編程輸出電壓保護(hù)、可檢測(cè)輸出短路保護(hù)、熱停機(jī)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(gè)具有最小的外部組件的緊湊解決方案。
