产品概述

描述

The STDES-50W2CWBC is a reference design that implements a Qi-compliant inductive wireless charger transmitter.

It supports two coils, which could work alternatively to increase the Rx positioning freedom.
The solution supports Qi EPP-compliant mode up to 15 W, featuring an ST proprietary protocol. It can also support 50 W or an even higher wireless power transfer.
The STDES-50W2CWBC is based on the STWBC2-HP high-integration, high-performance wireless charger system-on-chip.
It integrates: three pairs of half-bridge gate drivers, the dedicated DC-DC controllers that support buck, boost and buck-boost topologies, the high-performance Q-factor measurement hardware, the high-resolution main PWM controller, the dedicated Qi communication modulator and demodulator, the USB-PD controller, the buck DC-DC, and the charge pump.
It is suitable for one-coil and multicoil solutions in multiple topologies.
The STDES-50W2CWBC is a fully assembled reference design developed for performance evaluation only, not available for sale.
