Inverting and Non-Inverting Feedback Inputs  
1.0V Reference at Inputs  
easily be set up for such DC-to-DC voltage  
conversion circuits 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 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 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  
Operates from Supply Voltages of 2V to 40V  
Output Current up to 750 mA, Saturation Less

Configurations  
the switching frequency with  
a single external  
capacitor from <1 Hz to 100 kHz (typical).

Motor Speed Control  
Lamp Flasher  
The LM2578A is an improved version of the LM2578,  
offering higher maximum ratings for the total supply  
voltage and output transistor emitter and collector  
voltages.
