The TPS6215x family of synchronous buck dc-to-dc converters from Texas Instruments features a wide operating input voltage range from 3 V to 17 V and an adjustable output voltage of 0.9 V to 6 V. These devices are well-suited for many applications, such as standard 12-V rail supplies, embedded systems, and portable applications. Furthermore, the TPS6215x can be configured in an inverting buck-boost topology, where the output voltage is inverted or negative with respect to ground. This application report describes the inverting buck-boost topology in detail for the TPS6215x family. This topology can also be applied to the TPS6213x/4x/6x/7x converters.
