The LM2578A is a switching regulator which can easily beset up for such DC-to-DC voltage conversion circuits as thebuck, boost, and inverTIng configuraTIons. The LM2578A featuresa unique comparator input stage which not only hasseparate 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. Theoutput can switch up to 750 mA and has output pins for itscollector and emitter to promote design flexibility. An externalcurrent limit terminal may be referenced to either the groundor the Vin terminal, depending upon the application. In addition,the LM2578A has an on board oscillator, which sets theswitching frequency with a single external capacitor from <1Hz to 100 kHz (typical).
