SL1586H 4.5-45V/1A 600KHz 0.8VFB Synchronous DCM BUCK

General Description 

The SL1586H  is  a  low EMI signature, synchronous, step-down, switch-mode converter with internal power MOSFETs. It  offers a very compact  solution  to  provide 1.0A continuous current over a wide input supply range, with   excellent  load  and  line  regulation. SL1586H  achieves  low EMI  signature with well  controlled switching edges. Fault condition protection  includes programmable-output over-voltage protection, Constant on time  Mode,  and  thermal  shutdown. SL1586H  requires  a  minimal number of readily available standard external components. It is available in SOT23-6 package.
