3 A Wide input Adjustable Switching Regulator Project
This is the simple project os 3-A Wide-input Adjustable Switching Regulator circuit diagram. The PTN78060 is a series of high-efficiency, buck-boost, integrated switching regulators (ISR) from good old Texas Instruments (TI). The caseless, double-sided package has excellent thermal characteristics, and is RoHs compliant. The PTN78060 devices operate from a remarkably wide input voltage range: Note that the –A version supplies a negative output voltage. The devices provide high-efficiency stepdown voltage conversion for loads of up to 3 A. The PTN78060 devices are suited to a wide variety of general-purpose applications that operate off 12-V, 24-V, or tightly regulated 28-V dc power, hence are ideal for running low-voltage electronics from a very high power 24-V battery unit salvaged from an electric wheel chair and migrated into a robot. The output voltage VO can be set to any value over a wide adjustment range using a single external resistor RSET, using the equation RSET = 54....
