描述
 
ISL8033是一款双通道的集成电源控制器额定为每一个1MHz的通道3A 
降压稳压器,是任何低功耗低电压应用的理想选择。ISL8033A提供2.5MHz的操作更小,更夯实设计。渠道是
输入RMS电流和降低EMI,相位180° 。它是产生低输出电压下降到0.8V每一个优化。电源电压范围为2.85V至6V,允许使用一个单一的锂离子电池,三节镍氢电池或稳压5V输入。它有一个最低保证输出电流3A每个ISET的连接到VDD时。每个输出的输出电流设置ISET管脚选择。ISL8033,ISL8033A包括一双的低导通电阻P沟道和N沟道内部MOSFET,以最大限度地提高效率并减少了外部元件数量。100%dutycycle操作允许在3A小于250mV的压降。ISL8033,ISL8033A提供了一个独立的1ms的电源良好(PG)上电定时器。当关机,ISL8033,ISL8033A的输出电容放电。其它特点包括内部数字软启动,电源序列,的可控softstop输出放电过程中禁用,启用启动预偏置输出,最低压差为100%的最大占空比,100%的关税,为平稳过渡周期操作,小于8μA逻辑控制关断电流,独立的使能,过流保护和热关断。ISL8033,ISL8033A提供与1mm,最大高度24 LD 4mmx4mm的QFN封装。完整的转换占据小于5.46厘米2面积。
