DC-DC 3.7V-34V step up power transformer converter, power regulator

Features:

• Tiny small with dimension of 32x34x20mm
• Input and output between 3.7 V -34V, free adjustable.Seldom such small circuit can achieve such high voltage.
• Rated current is 2A while maximum input current is 3A. Power can reach as high as 15W and efficiency is around 90%.
  

Be Noted:

• please use thick wire connect the circuit. Clockwise voltage down and anti-clockwise voltage up.
• positive cannot meet the input and output, the output cannot be short-circuited.
• Output voltage must be limited within 35V, otherwise it will damage the circuit.
• Connect the input power source first, then adjust the output voltage then connect the load.
• The circuit is designed to step up voltage, so the input voltage should be lower than the output voltage to ensure the stability.
• The input and output voltage should be as close as possible. The Fomula is: input voltage*input current*efficiency = output voltage*output current

Attention: This circuit cannot be used on laptops which need at least 60W power

The relationship between the output voltage and current: Different input and output voltage and load would result different current. here is a test table from our engineer showing the performance:
