General Description

The SC485 is a dual output constant on-time synchronous-buck PWM controller intended for use in notebook puters and graphics cards.

Key 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 accuracy of 0.85% combined with a higher OVP thre.
