3W Wireless Power Receiver and WP3W-RK Transmitter Reference Kit Reference Kit Manual Features Description Fully-functional wireless power receiver and transmitter for IDTs wireless power reference kit targets applications ranging plug-and-play prototyping from 0.5 to 3W. The reference kit is comprised of both the transmitter (P9235A-R-EVK) and the receiver (P9027LP-R-EVK) High efficiency transfer up to 79% at 5V/600mA with three different coil size options supporting applications with Three coil size options meet various application requirements different form factors and power levels. The high-efficiency, 30 mm diameter for 3W applications turnkey reference design is supported by comprehensive online, 20 mm diameter for 2W applications digital resources to significantly ease design-in effort and enable 15 mm diameter for 1W applications rapid prototyping. Low BOM cost and high density PCB design for ultra-compact The receiver design is based on the P9027LP-R, a highly applications integrated, high efficiency solution suited to a wide range of Receiver (Rx) has 4-layer, performance-optimized PCB compact applications requiring up to 600mA load current. The reference layout for copying to system board layout has been optimized on a 4-layer PCB, compliant with Transmitter (Tx) has 2-layer, performance-optimized PCB wearable device layout rules and form factors. The ultra-compact reference layout for copying to system board form factor is ideal for rapid product prototyping. The active area 5.0V up to 0.6A output targets for wearable and many other of the P9027LP-R-EVK board is 5.7 mm x 5.7 mm and is ideal for lower power applications small form factor and thermally-constrained applications. Only 2 high-voltage capacitors necessary for Rx The transmitter design is based on the P9235A-R and can be LED indicator to indicate power transfer on both Rx and Tx powered from a micro-USB or other input voltage from 4.5V to boards 5.5V. The P9235A-R is based on a flexible 32-bit ARM Cortex- Break-away coil mount enables fast prototyping M0 processor with integrated full bridge power stage drivers and on-chip simultaneous voltage and current demodulation. It Programmable output voltage from 4.5V to 6V provides a low component count solution on an optimized 2-layer Over temperature protection and programmable over current hardware reference layout intended for seamless copy/paste to a protection on Rx board customer application board. The active area of the P9235A-R Selectable Tx input current limit capability for USB protection. board is 22.7mm x 21.2mm and is ideal for space-constrained, Programmable LED pattern on the Tx board low power transmitter designs. Supported by an extensive library of digital resources to ease Figure 1.
