IDTP9020 is a highly integrated single-
chip, WPC-compliant wireless power
receiver IC. The device receives an AC
power signal from compatible wireless trans-
mitters and converts it into a regulated 5V
output voltage, which can be used to power
devices or supply the charger input in mobile
applications. The IDTP9020 integrates a high-
efficiency synchronous full bridge rectifier,
high efficiency synchronous buck converter,
and control circuits used to modulate the
load to transmit WPC compliant message packets to the transmitter station to optimize power
delivery. In WPC mode, power delivery is limited to 5W in accordance with the Qi specification.
IDTP9020 may be operated in alternative modes where additional proprietary functions such
as advanced multi layered Foreign Object Detection (FOD), 2-way secure authentication, and
higher-efficiency control algorithms may be employed.
