From 5 V. to 12 V.

Other Parts Discussed in Thread: XTR117, TLV61046A

Hi,

I have DC 5V. (polarity positive, +5V. / 0V.), from this source,

I do DC 12V. (polarity positive, +12V. / 0V.), no need for isolation. 50 mA. enough

I will use the 12 V. voltage in the XTR117 supply.

How can I make it cheap and simple? it should be very cheap
what can i use?
regards,
Aslan.
