Continuous conduction mode (CCM) PFC controller with high voltage startup

L4985是一款用于升壓轉(zhuǎn)換器的峰值電流模式PFC控制器，采用專有的乘法器“模擬器”，除了創(chuàng)新型THD優(yōu)化器，還保證在所有工條件下具有非常低的總諧波失真（THD）性能。該器件采用引腳SO封裝，在符合EN61000-3-2和JEIDA-MITI標(biāo)準(zhǔn)的應(yīng)用中為以CCM模式運(yùn)行的升壓PFC預(yù)調(diào)節(jié)器提供高性能/低組件數(shù)的解決方案，功率范圍從幾百瓦到幾千瓦。\n\n 由于采用專有的關(guān)斷時(shí)間調(diào)制器，該器件能夠在所有工作條件下以準(zhǔn)固定頻率運(yùn)行。提供兩個(gè)選項(xiàng)：A為65 kHz，B為130 kHz。\n\n 800V高壓?jiǎn)?dòng)功能塊還包括用于將EMI濾波器的X電容降低到安全水平的電路。這使得該裝置能夠滿足安全規(guī)定 ? 峰值電流模式，以CCM模式運(yùn)行 \n? 800 V高壓?jiǎn)?dòng)，具有集成的輸入電壓感應(yīng) \n? 有源輸入濾波電容放電 \n? 專有乘法器“模擬器”，在所有工作條件（CCM和 DCM）下的最小線電流THD \n? 精簡(jiǎn)的外部組件 \n? 保護(hù)：反饋回路故障、OVP、OCP、電感飽和、過壓、欠壓（符合醫(yī)療SMPS標(biāo)準(zhǔn)） \n? 電感電流感應(yīng)? 禁用和低功耗功能 \n? 浪涌電流監(jiān)測(cè) \n? 通過軟啟動(dòng)實(shí)現(xiàn)平滑的啟動(dòng) \n? 1.2%（@ Tj = 25 °C）內(nèi)部參考電壓 \n? 65 kHz（A版本）和130 kHz（(B版本）開關(guān)頻率 \n?
