APEC (富鼎先进)推出高压Converter APE1862/A适用于车载娱乐系统

 2013-04-10

车用娱乐系统已由CD或卡式录音带,提升至目前车用蓝芽音响+免持听筒 / Car PC / DVD / MP3 / SD card / Car TV / GPS等。富鼎先进(APEC)针对车用影音娱乐系统,推出一款输出电流高达2Amp Converter IC适用于 12 or 24 VDC Cars & Trucks的应用。

 

富鼎先进(APEC)提供适合之高效率DC-DC buck之switch converter,其输入电源可从10V~58V,输出电压设定可从3.3V~56V且duty范围为0~100%的PWM控制,振荡频率约120KHZ / 250KHZ低涟波高效率降压转换器APE1862 / A

 

APE1862 / A具有Enable pin(Shut-down pin)并内建高端的MOSFET,以及能隙电压基准电路,比较误差放大电路及热保护(OTP)和输出短路保护(SCP)及限流保护(Current Limit)电路,且具有快速的瞬态响应。而热保护和限流保护电路则能保证芯片在异常状态下不受损。

 

该芯片具保护和极低的shutdown电流约500uA,并且采用ESOP-8无铅封装,可增强散热能力及缩小PCB的面积,以利成本降低。本产品已可供货。
