The WD1304E30 is a high efficiency,760 kHzswitch frequency,synchronous step-down DC-DC converter with delivering 3A currentcapability. The WD1304E30operates over a wide input voltage range from 4.5V to 18V and integrates main switch and synchronous switch with very low RDS(ON)to minimize the conduction loss.

The WD1304E30appliesConstant-on-time(COT)controlmode whichprovides very fastloadtransient responseand easy loop design.The WD1304E30integratesfull protections features includingshort-circuit protection, over-current protection, under voltage protection and thermal shutdownto make the part operatingsafely.

The WD1304E30is availablein SOT-23-6L package. Standard product is Pb-free and Halogen-free.
