DESCRIPTION
The TPS6107x devices provide a power supply
solution for products powered by either a one-cell,
two-cell, or three-cell alkaline, NiCd or NiMH, or
one-cell Li-ion or Li-polymer battery. Output currents
can go as high as 75 mA while using a single-cell
alkaline, and discharge it down to 0.9 V. It can also
be used for generating 5 V at 200 mA from a 3.3-V
rail or a Li-ion battery. The boost converter is based
on a fixed frequency, pulse-width-modulation (PWM)
controller using a synchronous rectifier to obtain
maximum
efficiency.
At
TPS61070 enters the power-save mode to maintain a
high efficiency over a wide load current range. At the
TPS61071 the power-save mode is disabled, forcing
the converter to operate at a fixed switching fre-
quency. The maximum peak current in the boost
switch is typically limited to a value of 600 mA.

The TPS6107x output voltage is programmed by an
external resistor divider. The converter can be dis-
abled to minimize battery drain. During shutdown, the
load is completely disconnected from the battery. The
device is packaged in a 6-pin thin SOT23 package
(DDC).
