Quick start procedure
The default configuration of the board has all additional features disabled. Jumper is placed in position 1-2.
In this configuration, ENABLE signal must be applied on X18 (max. 45 V). If another output voltage is required,
change the values of the voltage divider resistors R24, R25, and R26 according to the following equation:
V
OUT
R
24
+ R
25
+ R
26
∙ R
25
= V
REF
(1)
where
V
OUT
is the desired output voltage and
V
REF
= 300 mV is the feedback reference voltage. Correct device
functioning is achieved if voltages
V
FBH
and
V
FBL
on both terminals of R25 are greater than 3 V with respect to
ground.
Attention
:
On this board V
OUT
is set to 12 V by default. Increasing V
OUT
over the default level may damage
some components irreversibly.
The default configuration is depicted below:
