数据手册DataSheet 下载TEA1738LT 低压启动的在定频/CCM下工作的反激控制器.pdf

TEA1738是一系列用于反激拓扑结构的低成本开关电源(SMPS)控制器芯片。它们以峰值电流与频率控制模式运行。为降低电磁干扰(EMI),已经实施频率抖动功能。内部集成斜率补偿用于连续传导模式(CCM)。

产品特点
  • SMPS控制器IC,可实现低成本应用
  • 宽输入电压范围:12 V - 30 V
  • 引脚VCC上的集成过压保护(OVP)
  • 启动和重启时的电流极低(典型值10 μA)
  • 正常工作时电源电流低(空载典型值0.55 mA)
  • 过功率或高/低线路补偿
  • 可调过功率超时
  • 过功率后重启时间可调
  • 固定开关频率,带频率抖动以减小电磁干扰(EMI)
  • 中功率降频工作以提高电源效率
  • 固定最小峰值电流降频
  • 峰值功率运行增大频率
  • 针对连续传导模式提供斜率补偿
  • 较低且可调的过流保护(OCP)点
  • 可调软启动操作
  • 两种保护输入(如:输入欠压保护和过温保护)
  • IC过温保护
产品应用
  • 要求高达75 W的低成本高效所有电源应用解决方案
