i need single input dual output

input voltage is 5V (Vbus)

output volatge range is -15V to +15V

Current is not mandatory consider above 500 mA

i selected from TI TPS65130 but i need alternate part why because this part cost is high and internal circuit to large that 's why is not suitable to our applications please suggest me alternate part number and low cost and small circuit.

Hello naga reddy,

If you need more than 500mA output current, TPS65130 would not fit your needs because you need an inductor current that is close to 2A for this requirement. TPS65131 would get closer to your requirements.

I do not know of any other device that fulfills these requirements. We only could recommend 2 separate devices, one for boosting the 5V and another one for inverting the voltage.

Best regards,
Brigitte

You could consider an application such as this:

TPS54140 or TPS5424 could be substituted for TPS54160A. The design procedure would be the same.
