FP5139 100W DC Boost Step-up Adjustable Voltage Power Converter LED Voltmeter

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, suitable for LED strips and modules, but not for raw LEDs. Input: 3-35V DC 9A, Output: 3.5-35V DC 6A, Max Power: 100W when input and output both exceed 20V, otherwise 65W. Conversion Efficiency: Up to 96%. Low input voltage or a large difference between input and output voltage will degrade the current capacity and efficiency. Dimensions: 68x42x14mm, FP5139 IC with External MOSFET, 180KHz Switching Frequency Output voltage must be greater than input voltage, do not apply reverse polarity voltage, voltmeter works only when input is >= 4V.
