Description
LM1578A/LM2578A/LM3578A Switching Regulator April 1998 LM1578A/LM2578A/LM3578A Switching Regulator General .
The LM1578A is a switching regulator which can easily be set up for such DC-to-DC voltage conversion circuits as the buck, boost, and inverting config.
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 output can switch up to 750 mA and has output pins for its colle
Applications
* n Switching regulators in buck, boost, inverting, and single-ended transformer configurations n Motor speed control n Lamp flasher
