More Information
The UCD7231 high current driver is specifically designed for digitally-controlled, point-of-load, synchronous buck switching power supplies. Two driver circuits provide high charge and discharge current for the high-side NMOS switch and the low-side NMOS synchronous rectifier in a synchronous buck circuit. The MOSFET gates are driven to +6 V by an internally regulated VGG supply. The internal VGG regulator can be disabled to permit the user to supply their own gate drive voltage. This flexibility allows a wide power conversion input voltage range of 2.2 to 15 V. Internal under voltage lockout (UVLO) logic insures VGG is good before allowing chip operation.
