Overview
The TPS54292PWP is a dual-output, fully synchronous buck converter manufactured by Texas Instruments. This device is part of the TPS5429x series, which includes the TPS54290, TPS54291, and TPS54292 models. The TPS54292PWP operates from a 4.5-V to 18-V input supply voltage and supports output voltages as low as 0.8 V and as high as 90% of the input voltage. It is designed to support applications with a minimal number of external components, making it highly efficient and versatile.
