FS2462是泛海微自主开发的5A降压型同步整流芯片,频率500Khz,可以支持降压IC输出5V4.5A降压IC输出1.2V5A降压IC输出3.3A5A降压IC输出1.8V5A降压IC输出2.5V5A是国内首家大电流同步5A芯片,内部集成极低RDS内阻20豪欧金属氧化物半导体场效应晶体管的(MOSFET)。FS2462输入工作电压宽至4.75V到21V,输出电压1.0V可调至20V。5A的连续负载电流输出可保证系统各状态下稳定运行。其效率高达95%,满足各系统日益增强的节能和持久工作的求。内部振荡频率500KHz ,以保证对系统其它部分的EMI干扰最小。该芯片还具有软启动和逐周期过流保护、短路保护及过温保护功能。
FS2462采用标准SOP-8(Exposed Pad)封装,充分考虑大电流负载的散热问题。将IC所产生的热量从芯片内部传导至引线框架,并通过底部的散热片到达PCB板铜面提高散热性能极大的保证了芯片大电流状态下的稳定性。
FS2462应用领域:
1.网络通讯设备
2.LCDTV 液晶显示器
3.上网本 MID
4.机顶盒,消费类数码终端
5.RFID无线识别终端
