SC1154 Description
The SC1154 is a synchronous-buck switch-mode controller designed for use in single ended power supply applications where efficiency is the primary concern. The controller is a hysteretic type, with a user selectable hysteresis. The SC1154 is ideal for implementing DC/DC converters needed to power advanced ® microprocessors such as Pentium ll, in both single and multiple processor configurations.
