Lithium Battery Charge and 5V Boost Board (OMP1123) LIPO

Product Description

• Based on Chinese power bank (portable battery power supply) mature solution IC 5306, this is the demo board.
• Support Lithium battery charge on 2A rate. Single 2A boosted 5V output or two 1.2A 5V output, great for portable 5V device like Raspberry pi.
• SOP8 and simpe perpherial circuit, very good performace.
• Due to the simple perpherial circuit, it is easy to redesign and customize.
• Board interface inlcudes:
  • Two reserved USB output
  • MicroUSB 5V charge input
  • XH2.54 and 2-pin battery connecto
  • 4 LEDs battery volume indicator (100%, <75%, <50%, <25%)
  • Push button and light: short press to acivate from sleep, or long press to turn on/off light.
• Note:
  • Board will auto enter into sleep mode when no load.
  • Output two USB A port and XH2.54 smd connector is not soldered yet.

• Schematic avaialble on this page. IC can us to buy.
• Buck order price $1 for 50pcs+ order.
• Early design demo video (LED battery volume sequency is wrong, fixed on final board)
