3 Description
The TPS80010 device provides an integrated powermanagement 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 m A. 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...
