SL1588B
16V 3A 500KHz ECOT Force-CCM Sync Step-Down Regulator
General Description
The SL1588B is a high frequency, synchronous, rectified, step-down, switch-mode converter with internal power
MOSFETs. It offers a very compact solution to provide a 3A 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 SL1588B requires a minimal number of readily available, external components and is available in a space saving
SOT23-6 package.
