汽車用電流模式 PWM 控制器

CS2841B 提供實(shí)施離線固定頻率電流模式控制所需的所有必要特性，且外部組件極少。CS2841B（CS-2843A 的變體型號）專用于汽車運(yùn)行。8.0V（典型值）的低啟動閾值電壓和耐受 40V 汽車負(fù)載轉(zhuǎn)儲瞬變的能力對于汽車子系統(tǒng)設(shè)計(jì)至關(guān)重要。CS-2841 系列長期在汽車應(yīng)用中提供優(yōu)質(zhì)性能和高可靠性。CS2841B 結(jié)合了一個(gè)精確溫度控制振蕩器，帶有內(nèi)部微調(diào)放電電流，可最大程度減少頻率波動。還可實(shí)現(xiàn)大于 50% 的占空比。板上邏輯可確保啟用輸出級之前 VREF 得以穩(wěn)定。離子注入電阻提供更嚴(yán)格的欠壓鎖定控制。 ?
