Overview

www.
DataSheet4U.
com Dual Synchronous Buck DDR and DDR2 Power Supply Controller POWER MANAGEMENT Description The SC1486A is a dual output constant on-time synchronous buck PWM controller optimized for cost effective mobile DDR and DDR2 applications.
Features 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 applications, this voltage is set to 2.
5 volts, and in DDR2, 1.
8V.
