TPS65130RGER Buck-Boost Switching Regulator IC 3.2V, -2V 2 Output 700mA (Switch) 24-VFQFN
The TPS65130RGER is a dual-output split-rail power management IC from Texas Instruments, engineered to generate both positive and negative supply voltages from a single 2.7V to 5.5V input, making it ideal for LCD/OLED bias, portable instrumentation, and analog front-end power applications. It integrates a synchronous boost converter and an inverting buck-boost converter, capable of delivering adjustable outputs from ±2V to ±15V with up to 800mA switch current limit per rail, and achieves efficiencies up to 89% on the positive rail and 81% on the negative rail. Operating at a fixed 1.38MHz PWM switching frequency, it allows the use of small inductors and capacitors, reducing overall solution size while maintaining low output ripple. The device features independent enable pins (ENP/ENN) for flexible power sequencing, power-save mode for light-load efficiency, and integrated protection including overvoltage, thermal shutdown, and current limit. The 24-pin VQFN (4mm × 4mm) package ensures a compact footprint for space-constrained designs, while its -40°C to +85°C operating range makes it suitable for industrial and consumer electronics .
