開關(guān)電源 IC適用于低功率系統(tǒng); 針對最高30 W的通用電源設(shè)計\n集成功率開關(guān)：導(dǎo)通電阻48 Ω、耐壓650 V\n在通用市電下工作（80 V至276 V）\n靈活設(shè)計的可調(diào)節(jié)頻率\n用于穩(wěn)定負載不敏感型調(diào)節(jié)環(huán)路的RC振蕩器\n谷底開關(guān)具有最小開關(guān)導(dǎo)通損耗\n低功耗輸出下的降頻實現(xiàn)低待機功耗(< 100 mW)\n可調(diào)節(jié)的過流保護\n欠壓保護\n過溫保護\n短路繞組保護\n在初級側(cè)和次級側(cè)（光耦）均可做反饋的簡單應(yīng)用\n;

TEA152x系列STARplug產(chǎn)品是一款開關(guān)電源(SMPS)控制器IC，可直接采用整流后的通用市電工作。該器件采用高壓EZ-HV SOI工藝制造，并結(jié)合了低壓雙極性互補金屬氧化物半導(dǎo)體(BiCMOS)工藝。該器件集成高壓功率開關(guān)和直接利用整流后的市電電壓啟動的電路。內(nèi)置專門的谷底開關(guān)電路，可以做成極為高效的超薄插頭式電源。在多數(shù)的應(yīng)用中，TEA152x系列器件是作為電壓源使用。此處無需使用第二個電路。以最低的外部元器件成本，就可以實現(xiàn)電壓和電流源的組合\n
