Fonctionnalités et applications
The L5973ADTR is a step down monolithic power switching regulator with a switch current limit of 2 A so it is able to deliver more than 1.5 A DC current to the load depending on the application conditions.

The device uses an internal P-Channel D-MOS transistor (with a typical of 200 mΩ) as switching element to avoid the use of bootstrap capacitor and guarantee high efficiency. An internal oscillator fixes the switching frequency at 500 kHz to minimize the size of external components.

Features:

  • 2 A internal switch
  • Operating input voltage from 4 V to 36 V
  • 3.3 V / (±2%) reference voltage
  • Output voltage adjustable from 1.235 V to 35 V
  • Low dropout operation: 100% duty cycle
  • 500 kHz Internally fixed frequency
  • Voltage feedforward
  • Zero load current operation
  • Internal current limiting
  • Inhibit for zero current consumption
  • Synchronization
  • Protection against feedback disconnection
  • Thermal shutdown

Applications:

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