General Description<\/h3>\n\n\n\n

The EMP3431 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 with excellent load and line regulation. ECOT control easy loop design as well as very tight output regulation.
The EMP3431 requires a minimal number of readily available, external components and is available in a space saving SOT23-6 package.<\/p>\n\n\n\n
