Description

The LM3578AM is a Switching Regulator which can 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 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. In addition, the switching regulator has an on board oscillator, which sets the switching frequency with a single external capacitor from <1Hz to 100kHz (typical) and offers higher maximum ratings for the total supply voltage and output transistor emitter and collector voltages.
Inverting and non-inverting feedback inputs
Current limit and thermal shutdown
Up to 90% duty cycle
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
