ITEM NAME:60W DC Buck Boost Voltage Converter Constant Current Module Step Power Up / Down Descriptio n Description: Maintain stable output voltage and limit the output current over a wide range of input voltages. Great for general voltage conversion, battery charging, powering raw LEDs, automotive electronics, battery conversions, micro-controllers, and electronic projects. Input Voltage: 5-30V DC, Output Voltage: 0.5-30V DC, Max Load: 60W/4A Peak, 35W/3A Sustained (whichever is lower, amps or watts) Conversion Efficiency: Up to 88%, (our test results: 24V->12V1A: 86.5%, 12V->16V1.5A: 85%, 8V->16V1.5A: 74%). FP5139 IC with External MOSFET, SEPIC Topology, 180KHz Switching Frequency. Low input voltage or a large difference between input and output voltage will degrade the current capacity and efficiency (boosting 5V to 12V only works with very low current). The module will cut out if it is unable to source enough input current. Specifications: Dimensions: 65x32x21mm Color: As Pictures Show Package Included: 1 *Â DC Buck Boost Voltage Converter Note: 1.Due to the manual measurement and different measurement methods, the actual size could be slightly different. 2.Please be reminded that due to lighting effects and monitor's brightness/contrast settings etc, the color tone of the website's photo and the actual item could be slightly different.
