Overview
LM2639 5-Bit Programmable, High Frequency Multi-phase PWM Controller
February 2000
LM2639 5-Bit Programmable, High Frequency Multi-phase PWM Controller
General Description
The LM2639 provides an attractive solution for power supplies of high power microprocessors (such as Pentium II™, M II™, K6™-2, K6™-3, etc.
) exhibiting ultra fast load transients.
Compared to a conventional single-phase supply, an LM2639 based multi-phase supply distributes the thermal and electrical loading among components in multiple phases and greatly reduces the corresponding stress in each component.
The LM2639 can be programmed to control either a 3-phase converter or a 4-phase converter.
Phase shift among the pha...
