SC1163 Datasheet PDF - Semtech Corporation

DESCRIPTION
The SC1162/3 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.

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 requirements
• 1.5V or Adj. @ 1% for linear section
• 1.300V-2.05V ±1.5%; 2.100V-3.500V ±2%

APPLICATIONS
• Pentium® ll or Deschutes microprocessor supplies
• Flexible motherboards
• 1.3V to 3.5V microprocessor supplies
• Programmable dual power supplies
