General Description

15W-TX can deliver up to 15W as a highly-integrated single-chip wireless medium power transmitter IC. It can be configured to receive its input power from USB or AC adapter. Our chip integrates a power amp driver, a wide range DCDC converter, and communication controllers which use Amplitude Shift Keying (ASK) and Frequency Shift Keying (FSK). Our chip includes a 32-bit ARM Cortex M0 processor in order to offer high level of programmability according to its applications. Communication and control units (CCU) can accommodate WPC protocol including fault condition handling associated with power transfer. The CCU supports the foreign object detection (FOD) extension. Also, the chip includes over-temperature and voltage protection.
