Yan color: blue product weight: 16.53 g (packaging)

Package is installed, a single module electrostatic bag packing materials: FR4 + electronic components

Product performance:

1. Output current: 1.5 A (minimum), 2.2 A (typical)

2. The input and output voltage difference (VI - VO) : 40 VDC (maximum)

3. Adjustable output voltage range: 1.2 ~ 37 v

4. Working temperature: 55 ° C to + 150 ° C

5. : output current 1.5 A

6. Input voltage: 4.2 ~ 40 V

7. The working temperature: 0 ° C to 125 ° C

8. Characteristic frequency: 100 (MHz)

Using the tutorial:

Input mode: VIN input level, GND input cathode

Output: VOUT is output level, GND output is negative

The maximum output current, output current = 3 / (input voltage, output voltage)

Input voltage: 4.5 V - 40 V(limit our measured at up to 40 V),

Adjust way:first right after the input power supply (4.5 V -) between 40 V, output voltage with a multimeter monitoring and tuning potentiometer (general chronological booster, the backward turn step-down)
