The LTC1705 is a complete power supply controller for Intel Mobile Pentium processors. It includes two switching regulator controllers, each designed to drive a pair of N-channel MOSFETs in a voltage mode feedback, synchronous buck configuration, to provide the core and I/O supplies. The core controller includes a 5-bit DAC that conforms to the Intel Mobile VID specification. The IC also includes a low dropout linear regulator (LDO) that delivers up to 150mA of output current to provide the CLK supply. The LTC1705 uses a constant-frequency 550kHz PWM architecture, minimizing external component size and cost, as well as optimizing load transient performance. It provides better than 1.25% DC accuracy at its core output, and 2% at I/0 and CLK outputs. The high performance feedback loops allow the circuit to keep total output regulation within ±5% under all transient conditions. An open-drain PGOOD flag indicates that all three outputs are within ±10% of their regulated values. A shutdown circuit disables all three outputs if the RUN/SS pin is pulled to ground. In this mode, the LTC1705 supply current drops to below 100µA.
