Figure 2. P9242-G V3.8 Evaluation Board Detail
Note: The P9242-GB was used instead of the P9242-G IC on the P9242-G V3.8 Evaluation Board. The P9242-G has firmware pre-programmed
into one-time programmable memory and does not let users customize the firmware. The P9242-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 of the P9242-G V3.8 Evaluation Board using the P9242-G IC or the P9242-GB with external flash.
LED Pattern Selection
The P9242-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 as shown in the P9242-G-EVK schematics.

The LED patterns can be selected by setting the voltage on the GPIO_A3 pin through the resistor divider R61 and R62 (for options, see Table 1).
On the evaluation board, the GPIO_A3 pin is pulled up to GND through R62. R61 is unpopulated; therefore, option 1 is the default option.

External Temperature Sensing (TS)
The P9242-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.
Equation 1
Where NTC is the thermistor’s resistance (RTH1) and R60 is the pull-up resistor connected to the 3.3V supply voltage on the P9242-G Evaluation
Board. 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 on the P9242-G Evaluation Board.

External Buck Regulator
To operate at a fixed 127.7kHz frequency, the P9242-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 combined with the
external PWM signal are designed for the MP2229, and are not recommended to be changed. The resolution of the MP2229 is about 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 USB DCP or legacy USB 5V adaptors), the P9242-G-EVK supports such adaptors by turning off
the Buck regulator, and then enable a bypass path. The P9242-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 Oscillator
To guarantee that the switching frequency is fixed at an accurate 127.7kHz ±6Hz, an external clock IC and a crystal is used to guarantee that the
frequency will be in the range displayed in Table 2. The frequency of the clock IC or MEMS oscillator must be precisely 6.16791MHz to work with
the P9242-G. GPIO_B6 is used to synchronize with the external clock, and GPIO_B5 is recommended to be connected to GND when the external
oscillator is used. Table 2 contains a list of the recommended devices for clock/MEMS.

Resonant Capacitor
The P9242-G-EVK uses multi-layer ceramic capacitors as the resonant caps. A combination of 100nF/250V/X7R/1206 capacitors and
100nF/100V//C0G/1206 capacitors are used. If class II ceramic capacitors are used as the resonant capacitors, they need to be carefully selected.
The important considerations include the following:
 High voltage rating
 Stable DC characteristic
 Stable AC characteristic
 Stable temperature characteristic
