【产品】可调输入UVLO阈值电压的多功能控制器,关断电流仅10μA,宽输入电压范围2.97~60V
昱盛电子VP3681是一款多功能控制器,设计用于升压、SEPIC 和反激式电源转换器。该芯片的拓扑结构需要在外部增加一个低压侧N-MOSFET作为初级侧开关。该芯片除了逐周期限流功能外,电流模式控制方案还使其具有宽带宽和良好的瞬态响应特性。该芯片的电流限制功能可以通过一个外部电阻器简单地进行调节。
VP3681可以使用电阻器或任何外部时钟源将开关频率设置为100kHz和1MHz之间的任何值。该芯片可以在高开关频率下工作,以节省开发方案电路板的尺寸。 处于关断模式时,该芯片消耗的电流仅10μA,并允许电源有时序要求。 该芯片内置多种保护电路,例如热关断、欠压锁定、短路保护和过压保护。 该芯片的内部软启动电路可降低启动时的浪涌电流。
VP3681采用小型DFN10 3x3封装,如图1所示。该芯片的典型应用电路如图2所示,主要应用于便携式扬声器、离线电源、电池供电设备、汽车以及光伏逆变器等领域。
