Application information
Input voltage
There are two voltage supply pins:
VCC (pin L3), for controller voltage supply;
VIN (bank 1), for power circuit voltage supply.
VCC and VIN can be connected and supplied together;
if VIN is lower than 4.5 V, VCC must be supplied separately.
The recommended maximum operating DC input voltage is 14 V.
Auxiliary voltage
VAUX (pin J11) pin must be used to supply PRG and OS setting resistors.
No capacitor is required.
Inhibit function
SS_INL (pin L11) allows putting the device in stand-by mode.
With SS_INL lower than 0.5 V, the device is disabled and the current consumption is
reduced to 5 mA, for VIN = 12 V.
With SS_INL higher than 0.5 V the device is enabled.
Since SS_INL has soft-start function, it is mandatory to implement the inhibit function using
an open collector device (i.e. small signal transistor), to not influence the module behavior
(see
Figure 5.
