IC Features:

  • SX1308 DC boost module, small package, high efficience.
  • Adjustable output, maximium output 28V, internal embedded with very low RDS resistor, 100mR mosfet, provide up to 2A current.
  • Widely used for 3G product, digital, portable battery, battery powered device.
  • Short protection, over temperature production, etc.
  • 10K on board resistor to tune output voltage.

Board Features:

  • Maximium input voltage DC 2-24V
  • Maxiumium output voltage DC 2-28V
  • Frequency 1.2MHZ, efficiency up to 95%
  • Max. output current 2A.


  • Notice input from right and output on left.
  • Pin pad drill dia 2.0mm, pad 4.0mm
  • Board dimension 22×13 mm

R2 Update:

  • Current version update to R2, but image not yet updated.
  • Same pin definition.
  • Use high precise potentiometer, can precisely adapt on 0.01V, but more tuning work.
  • Higher quality inductor.
