SL1588A 18V 2A 1.2MHz ECOT PWM Sync Step-Down Regulator

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.
