The boost section delivers a positive output adjustable from 3.2 V up to 15 V, while the buck-boost section produces a negative output adjustable from -2 V down to -15 V. Each output uses its own 1.8 A switch, and the switching frequency is fixed at 1.38 MHz — high enough to keep the inductor and capacitor values small, without pushing switching losses through the roof. The datasheet layout recommendation is worth following — the pad is the main thermal path, and without it the junction temperature climbs fast under a 1.8 A load. No synchronous rectifier is used internally, so the external Schottky diodes take the switching losses — pick ones rated for the peak switch current and your output voltage. The base product number is TPS65131, and the 'RGET' suffix denotes the 24-VQFN package with the tape-and-reel option; the 'G4' suffix indicates green (RoHS) compliance.","metaTitle":"TPS65131RGETG4 Dual-Output DC/DC Converter, Boost/Buck-Boost","metaDescription":"Texas Instruments TPS65131RGETG4 dual-rail step-up/step-down regulator.
