DESCRIPTION
The SC1172/3 combines a synchronous voltage mode controller with a low-dropout linear regulator providing most of the circuitry necessary to implement two DC/DC converters for powering advanced microprocessors such as Pentium® II (Klamath) or Deschutes.
FEATURES
• Synchronous design, enables no heatsink solution
• 95% efficiency (switching section)
• 5 bit DAC for output programmability
• On chip power good function
• Designed for Intel Pentium®II VRM8.1 requirements
• 1.5V or Adj. @ 1% for linear section
APPLICATIONS
• Pentium®ll or Deschutes microprocessor supplies
• Flexible motherboards
• 1.3V to 3.5V microprocessor supplies
• Programmable dual power supplies
