具有 DHC 功能的 110W 交流输入、6 通道可调光 LED 驱动器
PMP4334 is the combo solution that provides single stage PFC and 6-channel LED drivers total solution with 110W output power. It delievers 350mA/channel with typical 50V output voltage. Overall PF>0.95 is achieved with the help of TM PFC UCC28810. Dynamic headroom control(DHC) feature of LM3463 controls DC input from UCC28810 and achieves high efficiency > 90% over wide range. It also presents good dimming linearity and accuracy. PMP4334 provides the dimming interface which can also support wireless dimming mode.
