Powering the Pentium™ VRE with the Si9145
Voltage Mode Controlled PWM Converter
BENEFITS
• First and only Intel-approved switching converter solution to provide static and dynamic
voltage regulation for the Pentium VRE microprocessor.
• Low cost • Efficiency greater than 89% at 7 A • Eliminates the need for heat sinks • Supplies maximum currents required by P54C • High operating frequency (recommended 375 kHz) allows use of the smallest possible inductors and
capacitors, resulting in lowest
voltage ripple and best transient response • Easily adjustable output
voltage to meet the different specs of P54C family.
• PCB layout available • Available in SO-16 surface-...
