FS2462是泛海微自主开发的5A降压型同步整流芯片

FS2462是泛海微自主开发的5A降压型同步整流芯片，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)。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 is a high-efficiency synchronous step-down

DC/DC converter that employs a special process

technique to obtain very low RDS(ON) for the internal

metal–oxide–semiconductor field-effect transistor

(MOSFET). The input operation voltage is in a wide

4.75V to 21V, and continuous load current capability

is 5A. Control circuit is designed by a particular

current mode which provides fast transient response

and eases loop stabilization.

This product has a very low standby current less

than 1μA in shutdown mode.
