Undervoltage lock out
Connecting a proper resistor (see par.
is possible to select two different thresholds for UVLO:
4.2 V/3.8 V for 5 V input range;
8.6 V/7.7 V for 12 V input range.
Program setting
Connecting a resistor from PRG (pin L7) to VAUX (pin J11), it is possible to select different
operation modes, according to the following table:
Table 12.
Voltage sensing
Using VSENSE (pin L2) it is possible to recover the voltage drop on VOUT PCB track.
Connect VSENSE in a point closed to the load (see
Using VSENSE connection, it will not recover the voltage drop on PGND PCB track.
Leaving VSENSE floating, the output voltage will be sensed at VOUT (bank 3) but its value
will be affected by an error, due to an internal resistor connected between VSENSE and
VOUT.
This error can reach +4.7%, depending on output voltage value, therefore it is advisable to
use VSENSE pin.
