Product Summary
The LM3578AM is a switching regulator which can easily be set up for such DC-to-DC voltage conversion circuits as the buck, boost, and inverting configurations. The LM3578AM features a unique comparator input stage which not only has separate pins for both the inverting and non-inverting inputs, but also provides an internal 1.0V reference to each input, thereby simplifying circuit design and p.c. board layout. The applications of the LM3578AM include: Switching regulators in buck, boost, inverting, and single-ended transformer configurations, Motor speed control, Lamp flasher.
