Hi,
For a project I am working on I need to generate a negative voltage from a single positive one. More precisely, I need -18V from +18V with at least 1A.
For the first prototype, I am using an LT1054 (http://www.ti.com/lit/ds/symlink/lt1054.pdf) powered @+15V and everithing works as expected. Unfortunately, the LT1054 can supply only 100mA and I cannot load the circuit as per requirements.
I am not able to find any Voltage Inverter IC which can provide the required current.
My questions:
1) How can I generate the negative voltage (-15V@ >=1A from 15V or even better -18V@ >=1A from 18V) without using either an IC or a transformer with two secondary windings?
2) Can you suggest me any voltage inverter with the required specs?
Thank you in advance.
