The UCD7242RSJR from Texas Instruments is a fully integrated power system designed to drive two independent buck power supplies. This digital dual synchronous buck power driver is compatible with TI Fusion Digital Power Supply Controllers, such as the UCD92xx family.
Key electrical specifications include a wide input voltage range of 4.75V to 18V, with operation down to 2.2V with an external bias supply. It supports up to 10A output current per channel and operates at switching frequencies up to 2MHz. The device features high-side current limit with a current limit flag, accurate on-die current sensing (±5%), and an onboard regulated 6V driver supply from V_IN.
Thermal management is supported by integrated thermal protection and a temperature sense output that is voltage proportional to the chip temperature. Undervoltage lockout (UVLO) and overvoltage lockout (OVLO) circuits ensure proper drive voltage. The UCD7242RSJR is rated for an operating junction temperature range of -40°C to 125°C.
Packaged in a 32-VQFN-HR (6x6 mm) surface-mount package, this component is suitable for applications such as digitally-controlled synchronous-buck power stages and high current dual-phase VRM/EVRD regulators for processors in desktop, server, telecom, and notebook systems.
