森利威爾 SL1585

30V 3A 500KHz Synchronous Step-Down Regulator

General Description

The SL1585 is a high frequency, synchronous, rectified, step-down, switch-mode converter with internal power

MOSFETs. It offers a very compact solution to achieve a 4A peak output current over a wide input supply range,

with excellent load and line regulation.

The SL1585 requires a minimal number of readily available, external components and is available in a space saving

ESOP8 package.
