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
