SC472B
SC472B is Single-Phase Single Chip Graphics Core Power Supply manufactured by SEMTECH.
POWER MANAGEMENT Description
The SC472B is a single-phase chip, high-performance PWM controller designed to power advanced graphic cores. On-chip support is provided for all of the Intel® integrated requirements, including Active Voltage Positioning, Slewrate controlled VID transitions, and VID-Controlled Sleep voltage settings. The SC472B implements hysteretic control technology which provides the fastest possible transient response .. while avoiding the stability issues inherent to classical PWM controllers. Eliminating the sense resistors reduces costs and PCB area, plus increases system efficiency. Integrated SmartDriver™ technology initially turns on the high-side...
