富鼎先進(APEC) 高壓Converter APE1862/A適用於車載娛樂系統

 2012-05-23

富鼎先進(APEC)提供適合之高效率DC-DC buck之switch converter,其輸入電源可從10V~58V,輸出電壓設定可從3.3V~56V且duty範圍為0~100%的PWM控制,振盪頻率約120KHZ / 250KHZ低漣波高效率降壓轉換器APE1862 / A。

 

 APE1862 / A具有Enable pin(Shut-down pin)並內建高端的MOSFET,以及,能隙電壓基準電路,比較誤差放大電路及熱保護(OTP)和輸出短路保護(SCP)及限流保護(Current Limit)電路,且具有快速的瞬態響應。而熱保護和限流保護電路則能保證晶片在異常狀態下不受損。

 

該晶片具保護和極低的shutdown電流約500uA,並且採用ESOP-8無鉛封裝,可增強散熱能力及縮小PCB的面積,以利成本降低。本產品已可供貨。
