UCD7242RSJT Description

Short technical summary and product information.

The UCD7242RSJT from Texas Instruments is a digital dual synchronous buck power driver designed for high-performance power management applications. This device integrates power switches and drivers, offering full compatibility with TI Fusion Digital Power Supply Controllers like the UCD92xx family.

 

Key electrical specifications include a wide input voltage range from 4.75V to 18V, with operation down to 2.2V possible with an external bias supply. It supports up to 10A of output current per channel and can operate at switching frequencies up to 2MHz. The driver features onboard regulated 6V driver supply, thermal protection, and temperature sense output.

 

Designed for demanding applications, the UCD7242RSJT includes features like high-side current limit with a current limit flag, UVLO and OVLO circuits for proper drive voltage, and accurate on-die current sensing with ±5% accuracy. It is rated for junction temperatures from -40°C to 125°C.

 

The UCD7242RSJT is available in a 32-VQFN-HR (6x6) surface-mount package. It is suitable for digitally-controlled synchronous-buck power stages and high current dual-phase VRM/EVRD regulators for processors in desktop, server, telecom, and notebook applications.
