使用 TDA 16846-2G
控制器实现支持低功耗待机、PFC 的开关模式电源的标准应用。 TDA 16846-2 经过优化,可控制带或不带功率因数校正(电流泵)的自由运行或固定频率
反激式转换器。为了在轻负载下提供低功耗,该器件会随着负载小步降低开关频率,以达到可调节的最小值(例如,待机模式下为 20 kHz)

Standard Application Using TDA 16846-2G Controller for Switch Mode Power Supplies Supporting low-Power Standby, PFC. The TDA 16846-2 is optimized to control free running or fixed frequency flyback converters with or without Power Factor Correction (Current Pump). To provide low power consumption at light loads, this device reduces the switching frequency in small steps with load, towards an adjustable minimum (e. g. 20 kHz in standby mode)
