The TPS80010 device provides an integrated power-management solution for 2-cell alkaline battery applications such as wireless mice, keyboards, and video game controllers. The VBUCK 1.8-V output is powered by a buck converter with a load capacity of 100 mA. A Power Good (PG) signal is generated when VBUCK is greater than 90% of its target output voltage. Integrated in the TPS80010 is an 80-mΩ load switch that can be connected to the VBUCK output, allowing more system design flexibility when connecting to multiple loads. The 3.1-V VBOOST output is powered by a boost converter. The VBOOST output voltage is post-regulated by the integrated 3-V LDO. This post-regulation provides a low-noise supply level through the specified battery range.
