Dual-Phase Single Chip IMVP-6 Vcore Power Supply
POWER MANAGEMENT Description
The SC452 is a single chip high-performance PWM controller designed to power advanced IMVP-6™ processors. On-chip support is provided for all of the IMVP-6 requirements, including Active Voltage Positioning, Geyserville-3 VID transitions, VID-controlled Deeper Sleep voltage setting, PSI# and DPRSL control, fast/slow C4 exit, and default Boot voltage. The SC452 www.DataSheet4U.com implements hysteretic control technology which provides the fastest possible transient response while avoiding the stability issues inherent to classical PWM controllers. Semtech’s proprietary Combi-Sense® technology provides a loss-less current sensing scheme which is extremely robust and easy to lay out.
