Product Description

DCDC 0.9V5V to 5V 600mA Step-Up Boost Converter Module

USB Output Charging Circuit Board for Power Bank & DIY Projects

The DCDC 0.9V5V to 5V 600mA StepUp Boost Converter Module is a highefficiency power supply solution designed to convert low input voltages into a stable 5V output for USBpowered devices[citation:1][citation:7][citation:10]. Ideal for DIY power banks, mobile chargers, and portable electronics, this compact module allows you to power 5V devices from single or double AA batteries, lithium cells, or other lowvoltage sources[citation:7][citation:10].

Input voltage: 0.9V to 5V DC - works with nearly depleted batteries
Output: 5V DC at up to 600mA (500-600mA typical)[citation:10]
No short circuit protection add selfrecovery fuse if needed[citation:7]

Wiring Guide

ConnectionDescription
IN+Positive input (0.9-5V DC)
IN-Ground
USB OUT5V output to USB devices

> Input can be from single AA battery (0.91.5V) or two AA batteries (2.43V)[citation:7]

Single AA: 200300mA output; Two AAs: 500600mA output[citation:7][citation:10]
Observe correct polarity - reverse connection may damage module

Performance Notes

# Output Current by Input Source[citation:7][citation:10]

  • 1x AA Battery: 200-300mA output
  • 2x AA Batteries: 500-600mA output
  • Lithium Battery (3.7V): Up to 600mA output
Higher input voltage yields higher output current capability
Module uses PFM control for efficient boost conversion[citation:1][citation:7]
