DC to DC power module (step up) Input 3.5V~10V Output 12V 1.25A New version*

For my application, I used a 9V battery for the input on this DC/DC converter in order to obtain the 12VDC output. Although not marked on the circuit board itself, the +/- Inputs are those closest to the LM2577 IC. I needed a physically small, efficient, converter to supply the necessary 12VDC input for the Mult-function 1CH RF Remote Control Tx/Rx set available from this site. I did not thoroughly test this DC/DC converter's output at various loadings, but for this purpose, it worked quite well. My application required a maximum load of 78mA at 12VDC, and this little converter performed as expected. No performance complaints and the circuit board package is very small.
