USB-PD/QC4.0 Development Kit A
Quick Start Guide for USB-PD/QC4.0 Development Kit
2. Safety requirements
This kit is to be used in combination with a QC4pDB1532 Portway adapter and a
TEA1936xDB1530 demo board. For supplying this application AC power with galvanic
isolation from the mains is strongly advised, as the TEA1936xDB1530 demo board is
connected to AC power. For supplying the TEA1936xDB1530 demo board a mains
isolated transformer/variac or an AC power source can be used.
Use a protective shield over the TEA1936xDB1530 demo board and never touch the
board when testing, i.e. with mains power on. After switching off the mains power, do not
touch the primary part of the board (red area), because the electrolytic buffer capacitors
will remain charged for several minutes. Only handle the board at the secondary side
(green) after testing, see Fig 2.

Beware of the primary circuit!
