в–  The LTCВ®1705 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 …
