Quick start procedure
The default configuration of the board has all additional features disabled. The jumper is placed in 1-2 position.
In this configuration the enable signal has to 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:
(1)
V
OUT
R
24 +
R
25 +
R
26
⋅ R
25 =
V
REF
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
respect to ground.
Attention
:
On this board V
OUT
is set to 48 V by default. Increasing V
OUT
over the default level may damage
some components irreversibly.
The default configuration is depicted below:
