LM2578AN IC, Buck Boost Switching Regulator, 750mA, PDIP-8.
The LM2578A 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.
Total Supply Voltage 50V
Collector Output to Ground −0.3V to +50V
Emitter Output to Ground (Note 2) −1V to +50V
Power Dissipation Internally limited: At elevated temperatures, devices must be derated based on package thermal resistance. The device in the 8-pin DIP must be derated at 95˚C/W, junction to ambient.
Output Current 750 mA
