Silicon revision
The silicon presented in this User Guide is ES1.
Description
The EN6362QI is a Power System on a Chip
(Power SoC) DC to DC converter with an integrated
inductor, PWM controller, MOSFETs and
compensation to provide the smallest solution size
in an 8x8x3mm 56 pin QFN module.

Instructions
board and the input voltage is monitored at
the board level. Please use INPUT
GROUND and INPUT VOLTAGE jacks to
connect the power.
• Please observe the correct polarity.
Warning:
Incorrect polarity of the
power supply may cause
permanent damage!
Warning:
2) Connecting the load
Power supply voltage
above 7V may cause
permanent damage!
• Connect the load to the OUTPUT GROUND
and OUTPUT voltage with patch cables, no
longer than 12 inches (30cm).
• Please observe the correct polarity.
Warning:
Do NOT hot-plug the
board;
the
resulting
overvoltage may cause
permanent damage!
3) Jumper Setting
• The board will arrive with NO jumper on the
J2 and one jumper on J1, in the 1V0
position. Connecting more than one jumper
on J1 will not damage the board – just drive
the output voltage higher.
1) Connecting the power supply
•
•
4) Power-up the board
Set the Power Supply to 5V/10A
Connect the power supply to the board
(make sure that the power supply is OFF)
with two patch cables, not longer than 12
inch (30cm). Using longer wires is possible,
provided that additional bulk is added to the
•
After all preparations above, the board
should be ready to perform.
Note: To measure the Bode Plot of the DC-DC converter, R9 must be replaced with 50Ω, while TP1, 2
and 3 should be used to connect the probes of the phase analyzer.

Test Recommendations
In order to get accurate measurements for sensitive nodes, small loop area (small antennae) are
recommended. Besides the built-in low inductance of the ground, the small loop area will collect less
EMI than the standard oscilloscope ground cables.
The EVAL board provides 3 test-points suitable for connecting the oscilloscope probe as described
above; these are:
•
•
•
TP28 – for the Switch Node (SW)
TP21 – for the Output Voltage (V OUT )
TP22 – for the Input Voltage (V IN ).
