SC1182CSWTR Datasheet PDF - Semtech Corporation

DESCRIPTION
The SC1182/3 combines a synchronous voltage mode controller with two low-dropout linear regulators providing most of the circuitry necessary to implement three 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® ll VRM8.1 requirements
• 1.5V, 2.5V or Adj. @ 1% for linear section

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