GENERAL DESCRIPTION
The SL1583 is a fully integrated, highefficiency 2A synchronous rectified stepdownconverter. The SL1583 operatesat high efficiency over a wide output currentload range. This device offers twooperation modes, PWM control and PFMMode switching control, which allows ahigh efficiency over the wider range of theload. The SL1583 requires a minimumnumber of readily available standardexternal components and is available in a6-pin SOT23-6 compliant package.
