Introduction: DC-DC Step Up Module (0.9V~4.8V) Tutorial

By Mybotic

Description

This DC-DC Step Up Module is a module that converts the input voltage from range 0.9V ~ 4.8V to 5V.


Features

  • Input voltage: 0.9 to 4.8 VDC
  • Maximum output voltage: 5 VDC
  • Maximum load current can be standed: 600mA
  • Directly connect via USB-A type Female socket to power devices
  • Small size: 34 mm x 16.2 mm x 7 mm
  • Up to 96% conversion efficiency
  • Status light indicator

Step 1: Material Preparation

For this tutorial, you need to have the following items:

  1. DC-DC Step Up Module
  2. Crocodile Clip
  3. Male-Male Jumper Wires
  4. DC Jack (Female)
  5. Power Adapter or Battery
  6. Multimeter

Step 2: Pin Connection

In order to observe the output voltage in 3 different voltage conditions, the DC-DC Step Down Converter is used to step down the voltage to 1.2V, 3.0V and 4.5V. To obtain the result, below is the steps:

  1. Connect the power supply 6V to DC-DC Step Down Converter and tuning the potential meter in order to get output voltage 1.2V (3.0V and 4.5V for the other turns).
  2. Connect the output voltage 1.2V to DC-DC Step Up module.
  3. Use the multimeter to check the output of DC-DC Step Up module.
  4. Repeat the step by using the different voltage.

Note: If you are using battery, the total battery voltage used should not exceed 5V.

Step 3: Result (1.2V)

Based on the picture above, it shows that the output voltage is fixed at 5V with low input voltage of 1.2V.

Step 4: Result (3.0V)

Based on the picture above, the input voltage have been increased to 3.0V and the output voltage at the USB port is constant at 5V.

Step 5: Result (5V)

Based on the picture above, the input voltage have been increased to 4.5V yet the output voltage at the USB port is constant at 5V.
