ltc1705EGN - Brand New Linear Technology Power Supply Controllers, Monitors
-
Description
The LTC®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.
