The Texas Instruments TPS65130RGERG4 is a dual-output DC-DC converter that generates both a positive and a negative adjustable rail from a single input supply. It combines a boost converter for the positive output and a buck-boost converter for the negative output, covering the topology pair that many mixed-signal designs need for op-amp, LCD bias, or sensor supplies. The positive output adjusts from 3.2 V up to 15 V; the negative output adjusts from -2 V down to -15 V. Switching frequency is fixed at 1.38 MHz, which keeps the inductor and capacitor values small enough for a compact PCB layout. The 700 mA switch current rating sets the practical load budget per rail — budget the inductor saturation current above that peak switch limit.
Package, footprint, and thermal management
Surface-mount assembly; the Tape & Reel (TR) packaging is the standard shipping medium for volume pick-and-place. No synchronous rectifier is integrated — the external Schottky diodes handle the rectification, so the bill of materials includes two diodes plus the inductor and output capacitors.
The 85°C ceiling is the ambient limit — junction temperature will be higher at full load, so derate the output current if the board runs hot.
