15W wireless charging solution based on IP6829 design

IP6829 supports PD input and fully integrated 5W/7.5W/10W/15W wireless charging transmitter SOC Overview
IP6829 is a wireless charging transmitter control SoC chip, compatible with the latest WPC Qi v1.3 standard, supports A11, A11a, MP-A2 coils, and supports 5W, Apple 7.5W, Samsung 10W, 15W charging. IP6829 detects the wireless receiver through analog ping and establishes communication with the receiver, then starts power transmission. IP6829 decodes the communication data packet sent from the receiver, and then uses the PID algorithm to change the oscillation frequency to adjust
the output power on the coil.
IP6829 integrates full-bridge drive circuit and full-bridge power MOS, voltage & current two-way ASK communication demodulation module; the solution is highly integrated, which can significantly reduce the solution size and BOM cost.
