Микросхема LM2578AN

Характеристики

LM2578ANThe LM2578AN/NOPB is a Switching Regulator which can easily be set up for such DC-to-DC voltage conversion circuit as the buck, boost and inverting configurations. The LM2578A 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 1V reference to each input, thereby simplifying circuit design and PC board layout. The output can switch up to 750mA and has output pins for its collector and emitter to promote design flexibility. An external current limit terminal may be referenced to either the ground or the Vin terminal, depending upon the application. In addition, the LM2578A has an on board oscillator, which sets the switching frequency with a single external capacitor from
