    TPS92074
    具有數(shù)字參考控制的非隔離式、降壓 PFC LED 驅(qū)動(dòng)器
    TPS92074 是一款混合功率因數(shù)控制器 (PFC)，此控制器針對(duì)無需相位調(diào)光兼容性的 LED 照明解決方案而進(jìn)行了優(yōu)化。 此器件使用一個(gè)內(nèi)部、低功耗、數(shù)字控制器來監(jiān)視轉(zhuǎn)換器已整流交流波形。 此控制器和數(shù)模轉(zhuǎn)換器 (DAC) 生成一個(gè)已同步三角基準(zhǔn)來調(diào)節(jié)輸出電流。 通過在線路周期上允許 LED 電流的變化，并且保持一個(gè)已調(diào)節(jié)總平均電流，可實(shí)現(xiàn)高功率因數(shù)解決方案。 通過使用一個(gè)恒定關(guān)閉時(shí)間控制，這個(gè)解決方案實(shí)現(xiàn)了低組件數(shù)量、高效率并自然提供了開關(guān)頻率的變化。 這個(gè)變化創(chuàng)建了一個(gè)仿真展頻效應(yīng)，從而簡(jiǎn)化了轉(zhuǎn)換器電磁干擾 (EMI) 簽名并可使用一個(gè)更小的輸出濾波器。 TPS92074 還包含一些標(biāo)  ? 取自 PFC 的受控基準(zhǔn)\n? 恒定 LED 電流運(yùn)行\(zhòng)n? 低典型運(yùn)行電流\n? 過壓保護(hù)\n? 寬溫度運(yùn)行范圍\n? 正在申請(qǐng)專利的數(shù)字架構(gòu)\n?  提供 8 引腳小外形尺寸集成電路 (SOIC) 封裝和 6 引腳薄小外形晶體管封裝 (TSOT);
