Charging Application User's Guide

1. Key features

The WCT1012VLF/WCT1013VLH Consumer MP-
A11_Rev1.0 (MP-A11_Rev1_SCH-32212_B, MP-
A11_Rev1_LAY-32212_B) wireless charging TX demo
(WCT-15W1CFFPD) is used to wirelessly transfer power
to a charged device. The charged device can be any
electronic device equipped with a dedicated Qi wireless
charging receiver.
The main parameters of the Wireless Charging
Transmitter (WCT) are:
• Support for QC 3.0 and USB PD 2.0/3.0 input.
The input voltage ranges from 5 to 19 V DC.
• The input voltage can drop down to 5 V DC
during the start-stop function.
• The nominal power delivered to the receiver is
15 W, up to 22 W (at the output of the receiver)
and compatible with a 5 W receiver.
• Designed to meet the Qi 1.2.4 specification.
• Operation frequency: 120 kHz ~ 130 kHz (the
default is 127.772 kHz) for Qi devices.
