18V, 5A, 650kHz, ACOT® 同步 Buck 转换器

RT7240A是一款ACOT(Advanced Constant On-Time)操作模式的同步降压型DC/DC转换器，输入电压4.5V至18V范围内，最大电流输出为5A。系统操作于ACOT模式下可在广负载变动范围内提供良好的瞬时响应，并于输出电容的选择上可选用具较小ESR的陶瓷电容，并确保整体系统表现的稳定性。此外，RT7240A在输入与负载变动情形下仍能提供良好的恒定操作频率表现，内建的整流开关可允许在输出在全负载变动范围内提供良好的转换效率。藉由侦测同步整流开关的端电压可达到逐周期形式的限流机制，并可藉由外部的电容设计达到缓启动效果，消除启动时产生过大的输入电涌。 • 具ACOT™ 操作模式提供快速的瞬时响应\n• 5A 输出电流\n• 进阶的恒定导通时间控制\n• 效率可达95%\n• 可调输出电压范围0.765V至8V\n• 逐周期电流限制\n• 过热保护\n;
