LT3470AIDDB#TRMPBF

LT®3470A is a micropower step-down DC/DC converter that integrates a 440mA power switch, catch diode and boost diode into low profile package. The LT3470A combines burst mode and continuous operation to allow the use of tiny inductor and capacitors while providing a low ripple output to loads of up to 250mA. Typical application include automotive battery regulation, power for portable products, distributed supply regulation, industrial supplies and wall transformer regulation.
