Overview
The TPS65130RGER is a dual-output DC-DC converter produced by Texas Instruments. This device generates both a positive output up to 15 V and a negative output down to –15 V, making it suitable for a wide range of applications. The converter operates with an input voltage range of 2.7 V to 5.5 V, allowing it to be powered from batteries or fixed voltage rails. It features a fixed-frequency PWM control topology and a power-save mode at light-load currents, ensuring high efficiency and reliability. The TPS65130RGER is packaged in a compact 4-mm × 4-mm VQFN-24 package, minimizing solution size and the number of external components required.
