| 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 SC1486 based solutions will require less output capacitance than competing fixed frequency converters. The frequency is constant until a step in load or line voltage occurs at which time the pulse density and frequency will increase or decrease to counter the change in output or input voltage. The output voltage of the first controller can be adjusted from 0.5V to VCCA. In DDR applications, this voltage is set to .
