MAX20307 Evaluation Kit
Evaluates: MAX20307
General Description
The MAX20307 evaluation kit (EV kit) is a fully assembled
and tested circuit board that demonstrates the MAX20307
eGaN driver IC. The driver is used to drive the high
and low-side switches of a synchronous buck converter
designed with space-saving EPC2039 eGaN FETs.

The following equipment can be used for more effective
testing of this EV kit:
Power supply with up to 60V capability
5V USB supply and a USB-B cable or 5V power
supply
Procedure
1)
2)
3)
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
Verify that shunts are installed on JU1, JU6, JU9,
JU10, and that JU11 is open.
Configure the power supply output from at least 7V
to no more than 35V.
Configure the function generator to output a 3.3V
square wave at the desired frequency and duty cycle.
Connect the positive lead of the power supply to TP2
and the negative lead to TP1. Turn on the power
supply.
Connect the function generator to the BNC connec-
tor J1. Turn on the function generator.
Using the DMM, measure the voltage at H8 and
confirm that it is the correct value set by V
IN
and the
duty cycle of the function generator.

MAX20307 Evaluation Kit
Evaluates: MAX20307
Detailed Description of Hardware
The MAX20307 EV kit is a fully assembled and tested
PCB demonstrating the MAX20307 as a buck converter.
An on-board 7805 5V regulator can be connected to the
VIN supply, allowing the EV kit to operate from one power
supply. By shunting JU9, the regulator receives power
through the VIN supply on TP2. While keeping JU11
open, shunting JU10 connects the regulator’s output to
the 5V rail of the PCB and powers the indicator LEDs and,
optionally, the MAX20307. Note that when using the 7805
regulators, VIN is limited to 35V. To avoid any risk of dam-
aging a device connected the USB port J4, make sure
JU11 is open before using the 7805 to power the board.
To measure the MAX20307’s supply current, remove the
shunt on jumper JU6 and apply 5V directly to TP3. An
ammeter in series with the 5V supply will measure the
current drawn by the MAX20307.
