FAN4800AS

功率因數(shù)控制器 (PFC) CCM + PWM 控制器，具有浪涌能力增強

高度集成的 FAN4800AS/CS/01S/02S 部件設(shè)計用于由升壓型 PFC 和 PWM 組成的電源。僅需要極少的外部組件便可實現(xiàn)各種保護(hù)/補償。采用16引腳DIP和SOP封裝。 PWM 可用于電流或電壓模式中。在電壓模式中，基于PFC輸出總線的前饋可減少輔助輸出的紋波。 與先前的產(chǎn)品相比，ML4800、FAN4800和FAN4800AS/CS/01S/02S具有較低的工作電流，可節(jié)省外部器件的功耗。FAN4800AS/CS/01S/02S具有PWM的49.9%精確占空比（最大值），從而能夠延長保持時間。該系列提供了欠壓保護(hù)和PFC軟啟動功能，但ML4800和FAN4800產(chǎn)品中; ? 與ML4800、FAN4800、CM6800和CM6800A保持引腳到引腳的兼容性。\n? 可為PWM配置電流模式或前饋電壓模式操作\n? 在一個IC中具有內(nèi)部同步的前沿PFC和后沿PWM\n? 低工作電流\n? 創(chuàng)新性開關(guān)電荷乘法器除法器\n? 平均電流模式，可實現(xiàn)輸入電流整形應(yīng)用\n?
