General Description

The SL1588M is a high frequency, synchronous, rectified, step-down, switch-mode converter with internal power

MOSFETs. It offers a very compact solution to provide a 2A continuous output current over a wide input supply

range, with excellent load and line regulation. ECOT PSM control operation provides very fast transient response

and easy loop design as well as very tight output regulation.

The SL1588M requires a minimal number of readily available, external components and is available in a space saving

SOT23-6 package.
