Fonctionnalités et applications
The L7980TR is a step down switching regulator with 2.5 A (minimum) current limited embedded power MOSFET, so it is able to deliver up to 2 A current to the load depending on the application conditions.

The input voltage can range from 4.5 V to 28 V, while the output voltage can be set  tarting from 0.6 V to VIN. Requiring a minimum set of external components, the device includes an internal 250 kHz switching frequency oscillator that can be externally adjusted up to 1 MHz.

Features:

  • 2 A DC output current
  • 4.5 V to 28 V input voltage
  • Output voltage adjustable from 0.6 V
  • 250 kHz switching frequency, programmable up to 1 MHz
  • Internal soft-start and enable
  • Low dropout operation: 100% duty cycle
  • Voltage feed-forward
  • Zero load current operation
  • Overcurrent and thermal protection
  • VFQFPN3x3-8L and HSOP8 package

Applications:

  • Consumer: STB, DVD, DVD recorder, car audio, LCD TV and monitors
  • Industrial: PLD, PLA, FPGA, chargers
  • Networking: XDSL, modems, DC-DC modules
  • Computer: Optical storage, Hard disk drive, Printers, Audio/graphic cards
  • LED driving
