数据: TPS54361 具有软启动和 Eco-Mode™ 的 4.5V 至 60V 输入、 3.5A、降压 DC-DC 转换器 数据表 (Rev. D)
TPS54361器件是一款集成高侧MOSFET的60V,3.5A降压稳压器。根据ISO 7637标准,该器件可承受高达65V的负载突降脉冲。电流模式控制提供了简单的外部补偿和灵活的组件选择。一个低纹波脉冲跳跃模式将无负载输出电源电流减小至152μA。当使能引脚被拉至低电平时,关断电源电流将降至2μA。
欠压锁定在内部设定为4.3V,但可通过使能引脚上的外部电阻分压器将之提高。输出电压启动斜坡受控制软启动引脚,该引脚还可被配置用来控制电源排序和跟踪。一个开漏电源正常信号表示输出处于标称电压值的93%至106%之内。
宽范围可调开关频率允许针对效率或者外部组件尺寸进行优化。逐周期电流限制,频率折返和热关断功能可在过载情况下保护内部和外部组件。
TPS54361器件采用10引脚4mm x 4mm WSON封装。
