LM2720 Datasheet (National Semiconductor)

LM2720, PWM Controller

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
