Infineon Technologies WLC1115 Wireless Charging Transmitter

Infineon Technologies WLC1115 Wireless Charging Transmitter is a highly integrated, Qi-compliant wireless power transmitter with integrated USB Type-C™ Power Delivery (PD). The WLC1115 complies with the Qi v1.3.2 standard for 15W applications and is compliant with the USB-PD 3.0 specifications. The WLC1115 includes integrated gate drivers for the buck and inverter power supplies that are necessary for wireless transmitter applications. The device supports a wide input voltage range and offers many programmable features for creating distinct wireless transmitter solutions.

The WLC1115 is a highly programmable wireless power transmitter and integrated USB-PD sink solution with an on-chip 32-bit Arm® Cortex®-M0 processor, 128KB flash, 16KB RAM, and 32KB ROM that allows most Flash available for user application use. The device also includes various analog and digital peripherals, such as an Analog-to-Digital Converter (ADC), PWMs, and timers. The inclusion of a fully programmable MCU with analog and digital peripherals enables scalable multi-coil wireless charging solutions for free positioning transmitter designs.

The Infineon Technologies WLC1115 Wireless Charging Transmitter is housed in an 8.0mm x 8.0mm QFN-68 package with an exposed pad for enhanced thermal performance.
