数据手册DataSheet 下载：TEA1731LTS 低压启动的在定频/CCM下工作的反激控制器.pdf

TEA1731LTS是一款用于反激拓扑结构的低成本开关电源（SMPS）控制器芯片。TEA1731LTS以峰值电流与频率控制模式运行。已经实现的频率抖动功能可以降低电磁干扰(EMI)。内部集成斜率补偿用于连续导通模式（CCM）。

产品特点
  • SMPS控制器IC，可实现低成本应用
  • 宽电压范围输入：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0.58 mA）
  • IC过温保护
  • 内部过功率超时
  • 过功率或高/低线路补偿
  • 固定开关频率，带频率抖动以减小电磁干扰（EMI）
  • 中功率降频
  • 固定最小峰值电流降频
  • 峰值功率运行增大频率
  • 保护输入（针对外部OTP和外部OVP）
  • 针对连续导通模式提供斜率补偿
  • 可调软启动
  • 较低且可调的过流保护（OCP）点
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
