    General Description
    2 W1 S" p3 e% [' `/ v: v( p" N9 T  oThe SL1588H is a low EMI signature, asynchronous, step-down, switch-mode converter with internal power MOSFETs.4 Q: Z5 W: B* k8 {& _* d9 w8 L
    It offers a very compact solution to provide a 2A continuous current over a wide input supply range, with excellent load1 U1 `. G) l  K/ ~7 C: x" N1 m
