What’s Inside
This Evaluation Board Kit contains the following materials:
? the ISL6227EVAL1 Evaluation Board
? the ISL6227EVAL1 Evaluation Board Setup
Procedure.
What is Needed
The following items will be needed to perform a complete
evaluation:
? 4 channel oscilloscope with probes
? 2 electronic loads
? 2 laboratory power supplies
? Precision digital multi-meters (DVM)
? Digital pulse generator
TABLE 1. Detailed Description of the Jumper Settings
Quick Setup Note:
? The VIN Power Supply must always be the FIRST
supply on and the LAST supply off to ensure start
up.
? The 5V V CC Power Supply must be between 5V ±
5%.
? Make sure the power is off before moving any
jumpers, except EN1 and EN2.
? Better connect/disconnect probes without
powering circuit
? Make sure the electronic loads are set at 0A
condition before the connection.
Step 1: Connect power supply and measurement
equipment.
1a. Connect VCC power supply
– Set the output voltage of the 5V adjustable power
supply to zero volts. Connect the positive terminal
(+) of the power supply to the VCC terminal J4.

* Use when Vin>5V, this will tie VIN pin to
the input voltage for feed forward and
program Ch2 PWM 90 phase lagging Ch1
Use when Vin<5V, this will tie VIN pin to
GND and program in phase PWM for CH1
and CH2
Connect the negative terminal (-) of the 5VDC
power supply to the GND terminal J1.
1b. Connect VCC measurement equipment
– Connect the positive terminal (+) of a DVM to the
VCC terminal J4. Connect the negative terminal (-)
of the DVM to the GND terminal J1.
? Do not apply power yet
1c. Connect VIN power supply
– Set the adjustable 24VDC output voltage to zero
volts. Connect the positive terminal (+) of the power
supply to the VIN terminals J2. Connect the
negative terminal (-) of the 24VDC power supply to
the GND terminal J3.
1d. Connect VIN measurement equipment
– Connect the positive terminal (+) of a DVM to one of
the VIN terminals J2. Connect the negative terminal
(-) of the DVM to the GND terminal J3.
? Do not apply power yet
