HIGH-EFFICIENCY, 1-CELL AND 2-CELL BOOST CONVERTERS
The converter output voltage can be adjusted from
1.5 V to a maximum of 3.3 V, by an external resistor

Battery During Shutdown of Converter
During shutdown, the load is completely isolated from

Integrated Low Battery Comparator
An autodischarge function allows discharging the

The TPS6101x devices are boost converters intended
for systems that are typically operated from a single-
