DESCRIPTION AND NOTES

This “Step Up/Boost Voltage Converter” operates over the DC input voltage range from (1.8V-5V) and produces a constant output voltage of 5VDC.

INPUT SIDE:

This converter comes with a “JST-PH 2-Pin SMT Right Angle Connector” (black in color) soldered in the PCB for better connection to the input. Connect the JST 2-pin cable (white head with red and black wires) to the “JST-PH 2-Pin SMT Right Angle Connector”. Then connect your red wire to the (+) positive input voltage and the black wire to the (-) negative input voltage. Note that there is a (+) positive and (-) negative sign on the Vin part on the PCB Boost Converter. (+) positive for your input positive voltage and (-) negative for your input negative voltage.

OUTPUT SIDE:

The converter also comes with a loose “USB A jack” that can be connected to the output to power any USB device. Note that you do not have to use the “USB A jack” for the output. You could just use a “2-pin 3.5mm terminal block” (blue in color) for the output. There are two golden holes in front of the 4 golden holes (where the USB 4 pins go into). Insert the “2-pin 3.5mm terminal block” there. Then put in your output positive and negative wires into the “2-pin 3.5mm terminal block”. There are two screws on top of the “2-pin 3.5mm terminal block” which you could use to tighten the voltage wires firmly for a fit connection. Note you could also just insert two wires (22AWG preferably) into those two holes instead of the “2-pin 3.5mm terminal block”. There is a (+) positive and (-) negative sign on the output part. (+) positive for your output positive voltage and (-) negative for your output negative voltage.

You could solder the “2-pin 3.5mm terminal block”, “USB A jack “, or wire (22AWG preferably) for better electrical connection.

NOTES:

The green light LED shows that the converter is receiving input power.

The red light LED indicates low input voltage below 3.2V.

FEATURES

• Synchronous operation. Could disconnect the output completely by connecting the EN pin to ground. This will completely turn off the output.
• Synchronous Conversion.
• 700 KHz high frequency operation.
• 2A (2.5 peak limiting) internal switch. Could get 500mA from as low as 1.8V input and at least 1000mA from 3.7V input.
• On-Board 500mA charge-rate ‘Apple/iOS’ data resistors. Solder in the included USB connector and you can plug in any iPhone or iPod for 500mA charge rate.
• Full breakout for battery in, control pins and power out.
• 90% operating efficiency. Low quiescent current; 5mA when enabled and power LED is on. 20uA when disabled (power and low battery LED are off).
• Perfect Universal power supply for all portable projects.
• Takes input fluctuating voltage and produces output constant voltage.
• Compact and Portable Design.
• Power-On indication LED.
• Low-Voltage indication LED.
• Long life.
• Easy to use.
• Durable.
• Safe.
• Well designed.
• Easy to install.
