Overview
Single-Phase Single Chip Graphics Core Power Supply
POWER MANAGEMENT Description
The SC473 is a single-phase chip, high-performance PWM controller designed to power advanced graphic cores.
Onchip support is provided that includes slew-rate controlled VID transitions.
The SC473 implements hysteretic control technology which provides the fastest possible transient response while avoiding the stability issues inherent to classical PWM www.
