POWER MANAGEMENT Description
The SC454 is a single-phase chip, high-performance PWM controller designed to power advanced IMVP-6 and IMVP6+ ™ processors. On-chip support is provided for all of the IMVP-6/6+ requirements, including Active Voltage Positioning, Geyserville-3 VID transitions, VID-Controlled Deeper Sleep voltage setting, PSI#, DPRSTP#, DPRSLP Control, Fast and Slow C4 Exit, and default Boot Voltage. The SC454 implements hysteretic control technology which www.DataSheet4U.com 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.
