• No user/operator instructions or data sheets.Find the download data by yourself, please make sure you consider whether you know the operation before buying. Size: 68x42x14mm, LTC1871 IC with External MOSFET.
• Conversion Efficiency: Up to 96%. Low input voltage or a large difference between input and output voltage will degrade the current capacity and efficiency.
• Boost voltage to a stable regulated output. Useful for a wide range of applications, such as powering 5V USB devices from a 3.7V lithium cell, powering higher powered electronics from a 12V battery, and a wide range of automotive and electronic projects. Constant voltage regulation, not for raw LEDs.
• Button to switch measurement of the input or output voltage, and LED indicates the current measurement of the input or output voltage; The nixie tube can be turned off by another button. Mentioned states are able to be memorized, is not lost even if the power is disconnected. (On-board marked "IN" LED is turned on, the nixie tube display input voltage value, "OUT" LED bright display is the output voltage value).
• Output voltage must be greater than input voltage, do not apply reverse polarity voltage, voltmeter works only when input is >= 4V.
