UCD7242-EP - Texas Instruments

UCD7242-EP Digital Dual Synchronous-Buck Power Driver

The UCD7242 is a complete power system ready to drive two independent buck power supplies (see Figure 1). High side MOSFETs, low side MOSFETs, drivers, current sensing circuitry and necessary protection functions are all integrated into one monolithic solution to facilitate minimum size and maximum efficiency. Driver circuits provide high charge and discharg.
