L5973D Description


The STMicroelectronics L5973D is a step-down monolithic power switching regulator with a minimum switch current limit of 2.5 A, allowing it to provide more than 2 A DC current to the load depending on the application conditions. The L5973D uses an internal P-Channel D-MOS transistor (with a type of 200 m?) as a switching element to avoid the use of a bootstrap capacitor and guarantee high efficiency.



L5973D Features


  • Zero loads current operation

  • Internal current limiting

  • Inhibit for zero current consumption

  • Output voltage adjustable from 1.235 V to 35 V

  • Low dropout operation: 100 % duty cycle

  • 250 kHz internally fixed frequency

  • Voltage feedforwardSynchronization

  • 2.5 A internal switch

  • Operating input voltage from 4 V to 36 V

  • 3.3 V / (±2%) reference voltage

  • Synchronization

  • Protection against feedback disconnection

  • Thermal shutdown



L5973D Applications


  • Networking: XDSL, modems, DC-DC modules

  • Computer: printers, audio/graphic cards, optical storage, hard disk drive

  • Consumer: STB, DVD, TV, VCR, car radio, LCD monitors

  • Industrial: changers, car battery, DC-DC converters
