SC2688
Description
Features
The SC2688 bines a synchronous voltage mode controller with two low-dropout linear regulators providing most of the circuitry necessary to implement three DC/DC converters for powering advanced microprocessors such as Pentium® III.
- Synchronous design, enables no heatsink solution 95% efficiency (switching section) Designed for embedded Pentium® III requirements 1.5V, 2.5V short circuit protected linear controllers
The SC2688 switching section features latched drive output for enhanced noise immunity, pulse by pulse current limiting and logic patible shutdown. The SC2688 switching section operates at a fixed frequency of 140k Hz, providing an optimum promise between size, efficiency and cost in the intended application areas.
Applications
Embedded Pentium® III microprocessor supplies.
The SC2688 linear sections are low dropout regulators with short circuit protection, supplying 1.5V for GTL bus and 2.5V for non-GTL I/O.
