DESCRIPTION

Up to 89% Efficiency at Positive Output

Voltage Rail

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

Up to 81% Efficiency at Negative Output

Voltage Rail

Power-Save Mode for High Efficiency at Low

Load Currents

Independent Enable Inputs for Power Up and

Power Down Sequencing

voltage range of 2.7

V to 5.5 V allows the

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.
