GENERAL DESCRIPTION

The SL1583 is a fully integrated, high

efficiency 2A synchronous rectified stepdown

converter. The SL1583 operates

at high efficiency over a wide output current

load range. This device offers two

operation modes, PWM control and PFM

Mode switching control, which allows a

high efficiency over the wider range of the

load. The SL1583 requires a minimum

number of readily available standard

external components and is available in a

6-pin SOT23-6 compliant package.
