SL1585B 

36V/3A 500KHz Synchronous Step-Down Converter


General Description

The SL1585B is a low EMI signature, asynchronous, step-down, switch-mode converter with internal power MOSFETs.

It offers a very compact solution to provide a 3A continuous current over a wide input supply range, with excellent load

and line regulation. SL1585B 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.

SL1585B requires a minimal number of readily available standard external components. It is available in ESOP8

package.
