DEVELOPMENT TOOLS
Ecosystem of Wireless Charging
Our membership in the WPC gives
us access to essential specifications
and IPs within the organization. This
access informs our wireless charging
development roadmap for Type A
and Type B transmitter and receiver
solutions. We supports customized
solutions according to differentiated
customer requirements. The medium
power wireless receiver and transmitter
reference designs contain optimized
software and are directly supported by
our technical solutions team.

WPR1500-LDO (40 x 40 mm)
Supports 5V/3A output following the
WPC “Qi” specification. With only
rectifier and LDO MOSFET outside
WPR1516 for system thermal design.
Most optimized BOM cost.
WPR1500-BUCK (40 x 40 mm)
Output with Buck architecture which
approves 5V/3A following WPC “Qi”
specification, and with capability to
support other output voltage and current
for various battery configuration.
