LM2720 5-Bit Programmable, High Frequency Multi-phase PWM Controller February 2000 LM2720 5-Bit Programmable, High Frequency Multi-phase PWM Controller General Description The LM2720 provides an attractive solution for power supplies of high power microprocessors exhibiting ultra fast load transients.
Compared to a conventional single-phase supply, an LM2720 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 LM2720 can be programmed to control either a 3-phase converter or a 4-phase converter.
Phase shift among the phases is 120˚ in the case of three phase and 90˚ wi...
