Solar Boost DC-DC 3V to 5V, 2.4V to 6V-10V adjustable power supply module

Features:

• Output voltage: 3.3V-10V, buyers may be adjustable, the default is 5V when delivery.
• Output current: Rated 500-700mA (Input 2.8V-3V, the output 500MA; (a single lithium input) output up to 700MA 
• Conversion efficiency: average 90% (the higher the input voltage, the higher the efficiency) 
• Output ripple: 50mV (MAX) 
• Operating temperature: Industrial grade (-40 ℃ to 85 ℃) 
• Full load temperature rise: 20 ℃ 
• Quiescent Current: 130uA 
• Load regulation: ± 1% 
• Voltage regulation: ± 0.5% 
• Output Mode: Standard USB 
• Size: 25 (including USB long-33MM) * 18.8 (W) * 11 (including potentiometer high 13) mm
• Small in size, big in power, output current 500-700MA and under-voltage indicator with high efficiency and average efficiency is up to 90%.

Under-Voltage Indicator function: 

• When the voltage is sufficient,indicator lights on, 
• When voltage is low to 2.7V, the lights go out, and you should charge as soon as possible, so as not to damage the battery.

How to Use:

• Boot mode: first connect input power supply, second the output 
• Input: IN +: positive, IN-: negative 
• Output Mode: Standard USB 
• Input voltage :0.9-10V 
• Adjusting: first connect input power correctly (0.9-10V) then using multimeter to monitor the output voltage and 
• adjust potentiometer (usually clockwise turn boost, inverse time step-down),
