DC/DC电源控制芯片

SCM1209A是一款原边推挽控制器，专门针对隔离接口应用中的小外形尺寸隔离电源而设计。只需匹配简单外围电路即可实现9-24V输入、3.3-24V输出，功率为1-3W的隔离电源。该芯片包含一个振荡器、两路驱动和两个功率开关管，每一路驱动控制原边一个绕组的电流流向。每一路包括一个功率NMOS管，两路交替驱动实现原边推挽控制，内部逻辑确保两个功率管开关之间的先开后合操作。此外，SCM1209A还集成了欠压和过温等多种保护功能，保证变换器的可靠性。其软启动特性可防止启机过程中的大电流冲击；短路计时和限流驱动的设计让容性负载能力和短路保护能力相互解耦；根据输入电压和温度的变化调节短路保护阈值，让容性负
