Part Number: TPS61046

Hello,

for my application i need +24 V and -24 V from a battery or a 5V-USB-Charger.

Can i use two of the TPS61046 or an other IC for my application?

Kind regards,

Steve

Hi Steve

Depend on the output current requirement, if several mA, I would suggest a 24V output boost and a phantom circuit to generate -24V. Please refer to the circuit in page 18 of this link "www.ti.com/.../tps61070.pdf".

Thanks for your answer.
Which component is intended for DS1?

Hi Steve

I would suggest 30V schottky diodes. I normally find the schottky diode in Mouser.
