The PTN78060, developed by Texas Instruments (TI), belongs to a series of high-efficiency buck-boost integrated switching regulator (ISR). Enclosed in a caseless, double-sided package with outstanding thermal properties, it also meets RoHS compliance standards. Notably, the PTN78060 devices operate over an impressively wide input voltage range.
Note that the —A version supplies a negative output voltage. The devices provide high-efficiency step-down 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 wheelchair and migrated into a robot.
