4. Start circuit
The start time from the power-on to the actual start can be set by using the values of R1 and C1. Too long start
time makes the power supply to rise slowly.
[Setting the start resistor R1]
1) When the overload shutting-off condition is kept, the shut-off bias current (OVP operating bias current) of the
AN8022L and AN8022SB is 550
μ
A (typical) at V
CC
=
10 V. Therefore, set the R1 as shown in the following
equation :

2) When automatic reset is desired after the overload shut-off, the standby current of the AN8022L and AN8022SB
is 70
μ
A (typical) at V
CC
=
12 V. Therefore, set the R1 as shown in the following equation :

[Setting the C1]
When the AN8022L or AN8022SB is started, the operating supply current of 7.5 mA is required at V
CC
=
18 V.
The current should be supplied with the discharge current of the C1 during the period from the soft start time
up to the time when the supply current is supplied from the auxiliary bias coil. Therefore, set the C1 as shown in
the following equation:
