This evaluation board is intended to demonstrate GaN FET technology and is for
demonstration purposes only and no guarantees are made for standards compliance.
There are areas of this evaluation board that have exposed access to hazardous high
voltage levels. Exercise caution to avoid contact with those voltages. Also note that
the evaluation board may retain high voltage temporarily after input power has been
removed. Exercise caution when handling.
When testing converters on an evaluation board, ensure adequate cooling. Apply
cooling air with a fan blowing across the converter or across a heatsink attached to
the converter. Monitor the converter temperature to ensure it does not exceed the
maximum rated per the datasheet specification.
See page 5 for operating guidelines.

Important Operating Guidelines
The TDTTP4000W066B is for evaluation purposes only and is not intended to be a
finished product and does not include all protection features found in commercial
power supplies. Additional warnings to keep in mind:
gAn isolated AC source should be used as input. An isolated lab bench-grade
power supply or the included AUX DC supply should also be used for the 12V DC
power supply. Float the oscilloscope by using an isolated oscilloscope or by
disabling the PE (Protective Earth) pin in the power plug. Float the current probe
power supply (if any) by disabling the PE pin in the power plug.
gUse a resistive load only. The totem-pole PFC kit can work at zero load with burst
mode and the output voltage will be swinging between 375V and 385V during
burst mode.
gThe evaluation board is not fully-tested at large load steps. DO NOT apply a very
large step in the load (>2000W) when it is running.
gDO NOT manually probe the waveforms when the board is running. Set up
probing before powering up the demo board.
gThe auxiliary VDC supply must be 12V. The evaluation board will not work under
10V or over 15V VDC, for example.
gDO NOT touch any part of the evaluation board when it is running.
gWhen plugging the control cards into the socket, make sure the control cards are
fully pushed down with a clicking sound.
gIf the evaluation circuit goes into protection mode it will work as a diode bridge by
shutting down all PWM functions. Recycle the bias power supply to reset the DSP
and exit protection mode.
gDO NOT use a passive probe to measure control circuit signals and power circuit
signals at the same time. GND1 and AGND are not the same ground.
gTo get clean VGS of the low side GaN FET, it is not recommended to measure the
VDS at the same time.
gIt is not recommended to use a passive voltage probe for VDS and VGS
measurements while simultaneously using a differential voltage probe for VIN
measurements, unless the differential probe has very good dv/dt immunity.

Step 3: Power-down the Board
gSwitch off the high-voltage AC power input
gPower off the DC bias
Probing
There are four voltage probing sockets to measure VGS and VDS of the GaN FET and
MOSFET low side, shown below.
Step 2: Power-up the Board
gInsert the control card
• LED1 ON indicates DSP power is on
• LED2 BLINKING indicates the DSP is
running
• LED3 ON indicates the DSP has stopped
running due to fault protection
(over voltage or current)
gConnect an electronic/resistive load to the corresponding marking (CN2).
The requirements for the resistive load are:
• At 115VAC input: 0W and ≤2200W
• At 230VAC input: 0W and ≤4400W
gConnect the 12VDC auxiliary supply (included) to the evaluation board
gVerify that both fans attached to the heatsink are running
gWith high-voltage power off, connect the high-voltage AC power input to the
corresponding marking (CN1) on the PCB; N and L (PE: potential ground)
gTurn on the AC power input (85VAC to 265VAC, 50Hz to 60Hz); minimum power
load for turn-on sequence is 350W
gMonitor CN2 output voltage with VDC meter to verify that 385V ±5V is generated
gLoad can be increased when AC supply is on and board is functional
Note:
See page 5 for important operating guidelines
By removing the jumpers and using a short wire to clamp the current probe, the PFC
inductor can also be measured.
