Principle of Operation and Application Hints
Voltage Control
The voltage loop is controlled via a first trans-conductance operational amplifier, the resistor bridge R1, R2, and the
optocoupler which is directly connected to the output.
The relation between the values of R1 & R2 should be chosen as following:
To Avoid the discharge of the load, the resistor bridge R1 & R2 should be highly resistive. For this type of
application, a total value of 100K
R2=100K , Vout=4.10V, Vref=1.21V, then R1=41.9K .
Note that if the low drop diode should be inserted between the load and the voltage regulation resistor bridge to
avoid current flowing from the load through the resistor bridge, this drop should be taken into account into the
above calculations by replacing Vout by (Vout + Vdrop).
optocoupler.
charger) to provide an accurate control of voltage and current. The above feedback loop is made with an
*R1=R2 x Vref / (Vout-Vref)
Where Vout is the desired output voltage.
