General Description
The SL1588A 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 control operation provides very fast transient response and
easy loop design as well as very tight output regulation.
The SL1588A requires a minimal number of readily available, external components and is available in a space
saving SOT23-6 package.
