ICs Generate All Motherboard Voltages

A pair of 3-in-1 power-supply voltage controller ICs is fully compliant with the latest VRM specification for Whitney- or Camino-based PC motherboards. The LM2637 and LM2638 ICs contain a 5-bit, synchronous step-down switching converter and two linear regulator controllers on one IC.Together, the ICs provide control of and protection for a minimum of six different voltages. The LM2638 includes circuitry that supports Instant-On PC designs. Both chips can generate the necessary voltages for the GTL+ bus, clock, graphics core, AGP interface, memory, or any other medium-to-low current loads.
