Semi’s 5V, WPC A11 Wireless Power Transmitter Evaluation Kit (EVK) offers the Industry’s
smallest footprint and lowest-BOM count Wireless Power Transmitter solution based on the PAC5220WP
IC. This solution has passed the Wireless Power Consortium (WPC) Compliance testing for version 1.1.2
of the low-power specification.
This design includes two versions of the EVK: high-performance (EVK-PAC5220WP-Qi-HPA11-V1) and
low-cost (EVK-PAC5220WP-Qi-LCA11-V1). Customers may select one of these designs according to
their end system needs. The high-performance (HP) version is optimized toward high performance for
efficiency and EMI, and the low-cost (LC) version is optimized toward system cost.
The EVK features Active-
Semi’s Power Application Controller™ PAC5220WP IC. This controller provides
all essential functions of WPC including receiver selection & identification, communication & control,
power transfer, guided placement through blinking LED and audio feedback. It also monitors input and
output power for load regulation, and WPC version 1.1 Foreign Object Detection (FOD). The solution also
provides over-current and over-temperature protection.

Semi’s WPC A11 EVK allows customers to perform fast prototyping of their end-product, taking
advantage of the turnkey solution provided with the hardware and preloaded firmware. In addition, with
Active-
Semi’s solution, the behavior of the dual-color LEDs, buzzer and other features are user-
configurable to meet their individual application needs.
The WPC A11 EVK with PAC5220WP also allows customer configuration of select features that can be
controlled by component changes on the customer PCB. Customers may change the LED behavior
during operation, dead-time for efficiency and EMI optimization and FOD detection thresholds.
