DESCRIPTION
A precise 5 bit digital to analog converter (DAC) allows to adjust the output voltage from 1.050 to 1.825 with 25mV binary steps. The high peak current gate drive affords to have fast switching to the external power mos providing low switching losses. The device assures a fast protection against load overcurrent and load over-voltage. An external SCR is triggered to crowbar the input supply in case of hard overvoltage. An internal crowbar is also provided turning on the low side mosfet as long as the overvoltage is detected. In case of over-current detection, the soft start capacitor is discharged an the system works in HICCUP mode.APPLICATIONS
