Description

NB: Use pure DC Voltages (like Batteries) for the Regulator/ Converter.

Constant Output Voltage:                                   5VDC

Output Current for 3V input:                             500Ma

Minimum output current for 12V input:         1000mA.

Weight:                                                                    0.088 ounce (2.5 g)

PCB dimensions:                                                  (0.7 X 1.3 X 0.2) inches

DESCRIPTION AND NOTES

This dual converter operates over the DC input voltage range from (3V-12V), moving from a Step Up/Boost Converter in the (3V-5V) range to a Step down/Buck Converter in the (5V-12V) range and produces a constant output voltage of 5VDC.

INPUT SIDE:              

This converter comes with a “2-pin 3.5mm terminal block” (blue in color) for better connection to the input. Connect the “2-pin 3.5mm terminal block” to the part that says Vin. Then put in your input positive and negative wires into the 2-pin 3.5mm terminal block. Note that there is a (+) positive and (-) negative sign on the Vin part of the PCB Dual Converter. (+) positive for your input positive voltage and (-) negative for your input negative voltage. 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”

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” or just two wires (22awg preferably) for the output. There are two holes in front of the 4 holes (where the USB 4 pins go into) where you could insert the“2-pin 3.5mm terminal block” or wires. There is also a (+) positive and (-) negative sign on the VOUT 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” and wires 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.
• 2MHz high frequency operation.
• 2A internal switch. Could get 500mA from as low as 3V and at least 1000mA from inputs as high as 12V.
• 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.
