森利威爾 SL1586C

30V/1.5A 1.4MHz 0.8VFB Synchronous BUCK

General Description

The SL1586C is a low EMI signature, synchronous, step-down, switch-mode converter with internal power

MOSFETs. It offers a very compact solution to provide 1.5A continuous current over a wide input supply range, with excellent load

and line regulation. SL1586C achieves low EMI signature with well controlled switching edges. Fault conditio

nprotection includes programmable-output over-voltage protection, Constant on time Mode, and thermal shutdown.

SL1586C requires a minimal number of readily available standard external components. It is available in SOT23- 6package.
