LM3578AN/NOPB

The LM3578AN/NOPB is a Switching Regulator can easily be set up for such DC-to-DC voltage conversion circuits as the buck, boost and inverting configurations. It 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 p.c. 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.

• Inverting and non-inverting feedback inputs
• Current limit and thermal shut down
• Duty cycle up to 90%
• Green product and no Sb/Br
