SC1182 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 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
