Using the Board
The evaluation board is easily prepared for use. Only minor preparations (just by soldering cables for DC supplies, input
PWM & /Fault + /UVLO feedback signals, proper cables for HV+/HV- high voltage bus, and load connections) are re-
quired. The evaluation board is having a default connection as shown in Table1 when shipped to customer. Customer is
free to select a different LED driving schemes and whether negative supply is used, as shown in the Table.

Notes:
*1. Whether J2 can be shorted depends on the drive signals (for connection to LED+ and LED-) from the Microcontroller.
*2. Since Miller Clamp function is built-in, -ve supply for VEE2 can be omitted, so VEE2 can be shorted to VE externally.
Note:
As the Desat diode’s breakdown voltage is rated at 1k V, IGBT must be selected with V
CES
<1 kV, and maximum HV+ voltage plus flyback voltage of
load inductor must be <1 kV).
