Overview
Dual Synchronous Buck For com Dynamic Voltage Transitioning
POWER MANAGEMENT Description
The SC485 is a dual output constant on-time synchronous-buck PWM controller intended for use in notebook computers and graphics cards.
Features include high efficiency and a fast dynamic response with no minimum on-time.
The excellent transient response means that SC485 based solutions will require less output capacitance than competing fixed frequency converters.
The two outputs are designed according to their target role.
Output 1 is designed to power IO or other static rails, whereas output 2 is designed to power rails requiring dynamic voltage transitioning.
Output 2 has a tighter DC ...
