DC-DC step-up module with selectable 5/8/9/12 V output, input from 2.5 V (pack of 5) – DFRobot DFR0952

Key features

• Output voltage selectable between 5, 8, 9 and 12 V by bridging or separating the two solder pads A and B on the front with a soldering iron (combinations are printed on the back); factory setting 12 V
• Conversion efficiency of 80% or higher
• Compact size, easy to integrate into devices
• On-board power LED showing the working status
• Note: the module has no reverse polarity protection and the input voltage must always be lower than the set output voltage, otherwise the module will be damaged

Technical specifications

• Type: DC-DC step-up (boost) converter
• Input voltage: from 2.5 V DC up to a value below the set output voltage
• Output voltage: 5 / 8 / 9 / 12 V DC (12 V by default)
• Output current at 3.7 V input: 1 A at 5 V; 0.5 A at 8 V; 0.45 A at 9 V; 0.3 A at 12 V
• Output current at 5 V input: 0.7 A at 8 V; 0.6 A at 9 V; 0.5 A at 12 V
• Conversion efficiency: ≥ 80%

Typical uses

Boosting battery voltage (for example 3.7 V lithium cells), power supply modifications, vehicle applications and powering LED lighting.
