TEA1738FT

低压启动的在定频/CCM下工作的反激控制器; SMPS控制器IC，可实现低成本应用\n宽输入电压范围：12 V - 30 V\n引脚VCC上的集成过压保护（OVP）\n启动和重启时的电流极低（典型值10 μA）\n低启动电压（典型值13.2 V）\n正常工作时电源电流低（空载典型值0.55 mA）\n过功率或高/低线路补偿\n可调过功率超时\n过功率后重启时间可调\n固定开关频率，带频率抖动以减小电磁干扰（EMI）\n中功率降频工作以提高电源效率\n固定最小峰值电流降频 \n峰值功率运行增大频率\n针对连续传导模式提供斜率补偿\n较低且可调的过流保护（OCP）点\n可调软启动操作\n两种保护输入（如：输入欠压保护和过温保护）\nIC过温保护\n;

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）。\n
