General Description
The SL1586A 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 force-CCM control operation provides very fast transient
response and easy loop design as well as very tight output regulation.
The SL1586A requires a minimal number of readily available, external components and is available in a space saving
SOT23-6 package.
