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 Pentiumfi 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 Pentiumfi ll VRM8.1 requirements.

◆ 1.5V, 2.5V or Adjustable @ 1 for linear section.

Applications

◆ Pentiumfi ll microprocessor supplies

◆ Flexible motherboards

◆ 1.3V to 3.5V microprocessor supplies

◆ Programmable triple power supplies
