Buck-boost & inverting regulators are not a specific brand but a category of voltage regulators used in power electronics. These devices are produced by various companies globally, such as Texas Instruments (USA), Analog Devices (USA), and STMicroelectronics (Switzerland). They serve industries like automotive, industrial automation, and consumer electronics, providing efficient voltage conversion for applications requiring step-up (boost), step-down (buck), or polarity inversion (inverting) of DC voltage. Key products include ICs and modules like the LM2577 (boost), LM2596 (buck), and LTC3105 (inverting).
