Product Summary
The L5973D013TR is a step down monolithic power switching regulator with a minimum switch current limit of 2.5 A so it is able to deliver more than 2 A DC current to the load depending on the application conditions. The output voltage of the L5973D013TR can be set from 1.235 V to 35 V. The high current level is also achieved thanks to an SO8 package with exposed frame, that allows to reduce the Rth(j-amb) down to approximately 40 ℃/W. The L5973D013TR uses an internal P-channel D-MOS transistor (with a typical Rdson of 250 mΩ) as switching element to minimize the size of the external components. The applications of the L5973D013TR include Consumer: STB, DVD, TV, VCR, car radio, LCD monitors, Networking: XDSL, modems, DC-DC modules, Computer: printers, audio/graphic cards, optical storage, hard disk drive and Industrial: changers, car battery, DC-DC converters.
