Nixie tubes need about ~180Vdc to light up and thus on most devices a DC-DC converter is needed. We designed here a simple DC-DC switching regulator capable of powering most of Nixie tubes.
The module is based on the MAX1771 Step-Up DC-DC Controller. This controller works up to 300kHz switching frequency and that allows the usage of miniature surface mount components. It accepts an input voltage from 2 to 16.5V and the output is factory configured to 12V. In this module the output voltage is configured higher at ~180Vdc using external resistors and a potentiometer.
