TPS80010 PMU for Alkaline Battery-Powered Applications
1 Features 3 Description
• 1.8-VBuckDC-DCConverter The TPS80010 device provides an integrated power-
1 management solution for 2-cell alkaline battery
• 3.1-VBoostDC-DCConverterwith3-VPost-
applications such as wireless mice, keyboards, and
RegulationLDO
video game controllers. The VBUCK 1.8-V output is
• Over91%ConversionEfficiency powered by a buck converter with a load capacity of
• Current-LimitedStart-UpforBothDC-DC 100 mA. A Power Good (PG) signal is generated
when VBUCK is greater than 90% of its target output
Converters
voltage. Integrated in the TPS80010 is an 80-mΩ
• LoadSwitchWithCurrent-LimitedTurnon
load switch that can be connected to the VBUCK
• Battery-LevelMonitorSwitch output, allowing more system design flexibility when
• 32-Pin,4-mm×4-mm ×1-mmVQFNPackage connecting to multiple loads. The 3.1-V VBOOST
output is powered by a boost converter. The
• ESDPerformanceTestedperJESD22
VBOOST output voltage is post-regulated by the
– 2000-VHuman-BodyModel integrated 3-V LDO. This post-regulation provides a
(A114-B, ClassII) low-noise supply level through the specified battery
– 500-V Charged-DeviceModel(C101) range.
