P9242-R Wireless Power Transmitter for WPC 1.2.2 15W Applications

A brief overview of IDT's high-efficiency 15W wireless power reference design kit, delivering the same ease of use and product support collateral that have become the hallmark of the Company’s wireless power kits. Supporting the latest Wireless Power Consortium (WPC) Qi 1.2.2 specification, the new kit’s compact wireless power transmitter and receiver operate at 87 percent efficiency, an industry best that rivals the performance of wired solutions and translates to reduced power dissipation and heat - resulting in faster battery charging times. The new kit features the IDT P9242-R transmitter and P9221-R receiver, flexible ARM-based devices that deliver fast charging capabilities combined with the industry’s highest level of integration.

With this latest 15W kit, IDT now presents an off-the-shelf library of turnkey wireless power solutions covering the range 1 to 15 Watts. The 15W kit is ideal for infrastructure that can benefit from higher power transfer—places like the home, office or café--as well as tablets, industrial portable scanners, Bluetooth speakers and mobile accessories such as charging pads, smartphone sleeves and cases.

TRANSCRIPT

Hello. My name is Julius Sarkis, Wireless Power Product Marketing Manager here at IDT. Today, I’ll be going over P9242 Wireless Power Transmitter Module, which is part of our 15W mass market kit. The 15W mass market kit is a comprehensive turnkey, easy-to-use reference design for rapid prototyping. Both transmitter and receiver are compact form factor with fully tested bill of materials, taking the guess work out of the components selection. The kit is comprised out of a P9242 transmitter and a P9221 receiver.
 
The P9242 is a new highly integrated 15-watt magnetic induction wireless power transmitter that is fully compliant to the WPC-1.2.2 specification. It supports WPC and PA2 coil configuration. The transmitter is a  highly compact solution with integrated drivers for external power FETs, integrated step-down regulator, and a current sense amplifier. In addition, it has an embedded 32-bit ARM processor providing flexibility and programmability while reducing the power in standby and sleep modes.
 
It also has selectable LED pattern and supports I2C interface to be able to read information such as voltage, current, frequency, and temperature. One of the key performance of the 9242 is the efficiency. The DC-to-DC system peak efficiency is 87% at 15 watts. The DC-to-DC is the efficiency from 9242 all the way up to the applied load or the 9221 receiver. The transmitter is available in QFN 6 x 6 48-pin package and it is rated for minus 40 to plus 85 degrees temperature.
 
The P9242 wireless power transmitter evaluation board is a four-layer board with one ounce of copper used on all layers, with a board thickness of 1.7 millimeters and smallest capacitors of resistors of 0201 size. The total active area is 2,430 mm2.
 
This concludes P9242-R Wireless Power Transmitter overview. For more information, please visit idt.com. I am Julius Sarkis and thank you for listening.
