TYPICAL APPLICATION CIRCUIT
Notes:
1. Set V
according to the following equation:
OUT
V
= V
( 1 +
)+ I

2. Choose the value for R as follows:
The maximum limit for R should be such that the cathode current, I , is greater
K
than the minimum operating current (80A) at V
*
IN(MIN)
The minimum limit for R should be such that the cathode current, I , does not
K
exceed 100mA under all load conditions, and the instantaneous turn-on value
for I
does not exceed 150 mA. Both of the following conditions must be met:
K
Rmin
(to limit instantaneous turn-on I )
K
Rmin
(to limit I under normal operating conditions)
