Icom IC-705 USB-C power delivery (rev.03 2025)

Block diagram

Functionality

  • 13.8V, max 3A output allows you to use TRX IC-705 with 10W output power
  • Universal - use any USB-C power source with 15V voltage profile (Apple divider 3, BC1.2 SDP, CDP and DCP detection)
  • LED indication of the output voltage for detecting the correct PD source
    • GREEN - the output voltage is OK, between 12 and 14.3V
    • RED - voltage is out of range - USB-C power delivery probably does not support the 15V/3A profile
  • filtering of the supply voltage against interference TRX IC-705
  • charging the internal battery from a USB-C PD power supply

Parameters

  • Dimensions 106 x 32 x 13mm
  • Weight 173g
  • Output Voltage 13,8V / max 3A (output current under overload conditions is constant)
