Description	Dual Synchronous Buck DDR and DDR2 Power Supply Controller
Datasheet	SC1486A_SemtechCorporation.pdf

The SC1486A is a dual output constant on-time synchronous buck PWM controller optimized for cost effective mobile DDR and DDR2 applications.

include high efficiency, a fast dynamic response with no minimum on time, a REFIN input and a buffered REFOUT pin capable of sourcing 3mA. The excellent transient response means that SC1486A based solutions will require less output capacitance than competing fixed frequency converters. The output voltage of the first controller can be adjusted from 0.5V to VCCA. In DDR.
