使用工字电感，2A贴片车充芯片

SD2004是一款输入耐压超过40V，在8V~34V输入电压条件下正常工作，并且能够实现精确恒压以及恒流的同步降压型DC-DC转换器。SD2004内部集成内阻为160mΩ的PMOS作上管、内阻为100mΩ的NMOS作下管，无需外部肖特基二极管，可连续输出2A电流。输出1A电流时系统转换效率可达93%，并可完整支持100%占空比。SD2004无需外部补偿，可以依靠自身内置稳定环路实现恒流以及恒压控制。SD2004提供5.15V固定输出电压版本，2.8A限流，外部最少仅需3个元件即可构成完整的降压系统。SD2004提供一个LED引脚作为输出状态指示：输出时常亮，关断输出时熄灭。SD • 输入耐压高达40V\n• 2A连续输出电流\n• 内置软启动\n• 外部最少仅需要3个元件\n• 欠压保护(UVLO)\n• 过压保护(OVP)\n• SOP-8L封装形式\n\n;
