The LM2578A is a switching regulator and other DC-to-DC voltage buck, boost, and inverting configuration conversion circuits that can be easily set. The LM2578A features a unique comparator input stage that not only has independent pin-inverting and non-inverting inputs, but also provides an internal 1.0V reference for each input, simplifying circuit design and printed circuit board layout. The output can switch up to 750 mA to collector and emitter, facilitating design flexibility. An external current limit terminal may be referenced, either on ground or V at the terminal, depending on the application. In addition, the LM2578A board oscillator, this one from
The LM2578A is an improved version of the LM2578 that provides higher total supply voltage and maximum ratings for the emitter and collector voltages of the output transistor.
