LM2633 Advanced Two-Phase Synchronous Triple Regulator Controller for Notebook CPUs August 2001 LM2633 Advanced Two-Phase Synchronous Triple Regulator Controller for Notebook CPUs General Description The LM2633 is a feature-rich IC that bines three regulator controllers - two current mode synchronous buck regulator controllers and a linear regulator controller. The two switching regulator controllers operate 180˚ out of phase. This feature reduces the input ripple RMS current, resulting in a smaller input filter. The first switching controller (Channel 1) Features an Intel mobile CPU patible precision 5-bit digital-to-analog converter which programs the output voltage from 0.925V...
