DESCRIPTION
The TPS80010 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 above 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.
