DC-DC boost power supply module, 3845 scheme, widely used in Nixie tubes, Nixie tube clock, Vacuum tubes 6E2, 6E1, 6E5 audio level indication.
Input voltage 10-24V, output voltage 90V-250V adjustable. Easily drive more than 10pcs vacuum tubes. Low heat, no need to add heat sink.
The higher the output voltage, the lower the output power and the lower the efficiency. When the output voltage is 170V, the maximum output current is 25mA.
With the shutdown function, the SHUT pin through the MCU connected to the high level off the booster board, if not use, Vacant or connect to GND.
