2 layer board of 0.96 x 1.21 inches (24.3 x 30.6 mm)

Total Price: $5.75

Simple 555 charge-pump circuit to create a negative tracking split supply voltage that mirrors the single supply input voltage.

It was an implementation of this design: http://www.syscompdesign.com/Negative-Tracking-Power-Supply_b_89.html for testing.

NOTE: This circuit isn’t stable and will generally go up-in-smoke. I advise forgetting this one and use the LM2662 based circuit instead, which works well.
