Description
The P9241-G-EVK Evaluation Kit demonstrates the features of the
P9241-G 5 to 10W Wireless Power Transmitter (TX) with a fixed
frequency. It is intended to evaluate the functionality and perfor-
mance of the P9241-G when combined with a WPC Qi Baseline
Power Profile (BPP) power receiver in a wireless charging system
capable of providing 7.5W wireless charging for iPhone mode or
10W wireless charging for Android proprietary modes. The P9241-
G-EVK offers the flexibility to select parameters, such as the LED
pattern, power-loss foreign object detection (FOD) threshold, and
external temperature sensing function. The printed circuit board
(PCB) has four layers. It can be used with the user’s WPC-1.2.4
compliant receiver.
The high-efficiency, turnkey reference design is supported by
comprehensive online, digital resources to significantly expedite
the design-in effort and enable rapid prototyping.

Note: The P9241-GB IC is used instead of the production P9241-G IC on the P9241-G V1.2 Evaluation Board. The P9241-G IC has firmware
pre-programmed into the one-time programmable memory and does not allow users to customize the firmware. The P9241-GB also offers a
pre-programmed bootloader that must be used in conjunction with an external flash. Firmware is loaded into the external flash. Users can
customize the firmware in external flash. There is no functionality difference for the P9241-G V1.2 Evaluation Board using the P9241-G or the
P9241-GB with external flash.

LED Pattern Selection
The P9241-G-EVK uses two LEDs (LED1 and LED2 (see Figure 1) to indicate the power transfer status, faults, and operating modes. The LEDs
are connected to the LED1 and LED2 pins of the P9241-GB (see note below Figure 2) as shown in the P9241-G-EVK schematics.
The LED patterns can be selected by setting the voltage on the GPIO_A3 pin (see Table 1) via the resistor divider R61 and R62 (for location,
refer to Figure 3 and Figure 4). On the Evaluation Board, the GPIO_A3 pin is pulled down to GND through R62. R61 is unpopulated; therefore,
option 1 is the default option.

External Temperature Sensing (TS)
The P9241-G includes an optional temperature sense input pin, TS, that is used to monitor a remote temperature, such as for a coil or a battery
charger. The TS pin voltage can be calculated using Equation 1.

The over–temperature shutdown is triggered if the voltage on the TS pin is lower than 0.6V and recovers at 0.8V. The RTH1 is not populated

External Buck Regulator
To operate at a fixed 127.7kHz frequency, the P9241-G-EVK has adopted an MP2229 buck IC to adjust the power transfer between the
transmitter and receiver. GPIO_A4 and GPIO_B4 are assigned to adjust the MP2229 FB control. The MP2229 is operating at a fixed 500kHz
frequency on the board. The buck regulator power stage is designed to accommodate a wide range of input voltages. The feedback loop and
the external PWM signal are designed for the MP2229 and changing this circuit is not recommended. The resolution of the MP2229 is
approximately 35mV. The buck and external components in the PCB layout should be isolated from any noise generating circuits.

Bypass Path of the External Buck Regulator
When the adaptor voltage is 5V only (such as for USB DCP or legacy USB 5V adaptors), the P9241-G-EVK supports such adaptors by turning
off the buck regulator and then enabling a bypass path. The P9241-G will be operating in a variable frequency mode to adjust the total power
transferred. GPIO_A4 is used to turn on the bypass path.

External Crystal Circuit
To guarantee that the switching frequency is fixed at an accurate 127.7 kHz, two different types of crystals can be used to guarantee that the
frequency will be in the range defined in Table 2. Only one crystal is necessary; a choice can be made between the crystals designated as Y1
and Y2 in Table 2 by comparing cost and package size. By default, Y1 is populated on the P9241-G EVK board. GPIO_B6 and GPIO_B5 are
used to synchronize with the external crystal. Table 2 gives a list of the recommended devices for the crystal.

Resonant Capacitor
The P9241-G-EVK can use four 100nF/100V/NPO/1206 capacitors as the resonant cap for best performance. For a lower cost solution, only
one film capacitor (400nF/100V or 250V) is used by default. For film capacitors used as the resonant capacitors, they must be carefully selected.
The important considerations include the following:
 Metalized polypropylene type
 High voltage rating
 Stable DC characteristic
 Stable AC characteristic; AC RMS rating de-rates based on operating frequency
 Stable temperature characteristic; voltage rating degrades above 85°C, so it is better to use it at temperatures < 85°C
 The ESR will be higher than that of 4 or 5 parallel C0G capacitors; therefore efficiency might be impacted

Selection of Input Source and Operation Mode
The P9241-G-EVK supports different types of AD/DC adaptors and connectors. A shunt on the jumpers identified in Figure 13 can be used to
select the USB-Micro connector, USB-C connector, or DC jack adaptor. To select the proper jumper settings, refer to Figure 13.
