General Description
The SL1588H is 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. SL1588H 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.
SL1588H requires a minimal number of readily available standard external components. It is available in SOT23-6 package.
