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.
