Texas Instruments UCD7232
The UCD7232 high current driver is specifically designed for digitally-controlled, point-of-load, synchronous buck switching power supplies. The MOSFET gates are driven by an internally regulated VGG supply. The internal VGG regulator can be disabled to permit the user to supply their own gate drive voltage.| Part No. | UCD7232 |
