Power Controller Serves Pentium II- and III-Based Notebook PCs

The SC1406 is a hysteretic-mode power supply controller for notebook PC designs using Pentium II and III CPUs. The device is said to be the first of its kind to incorporate two on-chip linear regulator drivers for powering system clock and I/O. It provides efficiency ratings to 90% over a wide load range. For enhanced stability, an extremely fast comparator with 25-ns typical propagation delay and an output voltage tolerance of less than 1% is included on the chip.The LDO drivers provide 500 mA and 100 mA of steady dc current with external PNP transistors with output voltage settings of 1.5V and 2.5 V, respectively.
