SL1588H降壓芯片36V降壓5V2A同步降壓IC

小鄭

General Description
The SL158 8 H a low EMI signature, asynchronous, step-down, switch-mode converter with internal power MOSFETs.
It offers a very compact solution to provide a 2A continuous current over a wide input supply range, with excellent load
and line regulation. S L158 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.
SL158 8 H requires a minimal number of readily available standard external components. It is available in SOT23-6 package.
