The WD1305E20 is a high efficiency,500kHzswitch frequency,synchronous step-down DC-DC converter with delivering 2Acurrentcapability. The WD1305E20operates over a wideinput 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 WD1305E20appliesConstant-on-time(COT)controlmode whichprovides very fastloadtransient responseand easy loop design.The WD1305E20integratesfull protections features includingshort-circuit protection, over-current protection, under voltage protection and thermal shutdownto make the part operatingsafely.
The WD1305E20is availablein SOT-23-6L package. Standard product is Pb-free and Halogen-free.
