Description 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. Dimension: 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. Schematic and datasheet see on this page.
