电流控制型降压开关调节器

S264S是 Power MOSFET内置的同步整流型开关调节IC。为了实现轻负载时高效率，轻载时采用Pulse Skip动作模式。此控制方式和峰值电流控制方式相比，使用陶瓷电容等低ESR的电容可以更稳定的动作。并且搭载有过电流保护，低电压输入欠压保护，过热保护等全面的保护功能。可以构成电子元件少而消减实装面积的开关调节器电路。 ・同步整流型\n・动作模式\n　-定常时：电流模式型 PWM控制\n　-轻载时：Pulse Skip动作模式\n・最大效率（VIN = 12 V、VOUT = 5 V）\n　-定常时：94 %\n　-轻载时（Iout = 10 mA）：86%\n・采用低ESR陶瓷电容稳定输出\n・消减外部电子元件数（5V固定输出）\n・可以通过外接电容来设置软启动时间\n・使能功能\n・频率限制功能（轻载时，Pulse Skip的频率限制在28kHz）\n・保护功能\n　-过电流保护（OCP）：垂下型、自动恢复\n　-过热保护（TSD）：自动恢复\n　-低电压输入时误动作防止回路（UVLO）\;
