DESCRIPTION
The TPS65130/1 is dual-output dc-dc converter gen-
erating a positive output voltage up to 15 V and a
negative output voltage down to -15 V with output
currents in a 200-mA range in typical applications,
depending on input voltage to output voltage ratio.
With a total efficiency up to 85%, the device is ideal
for portable battery-powered equipment. The input

of
2.7
V
TPS65130/1 to be directly powered from a Li-ion
battery, from 3 cells NiMH/NiCd or alkaline batteries.
The TPS65130/1 comes in a small 4 mm x 4 mm
QFN-24 package. Together with a minimum switching
frequency of 1.25 MHz it enables designing small
power supply applications because it requires only a
few small external components.
