Chip that produces +ve and -ve output from +ve input

[rvnd5d]

Hello All,
I want to design a circuit where I want both +ve and -ve supply voltages. However, I do not want to use dual supply. Is there any circuit or chip that produces a dual polarity output with single polarity input.
I actually found one.
MURATA POWER SOLUTIONS - NDTD1212C
Is there any other chip that performs like this?

Thanks in advance.
