Fonctionnalités et applications

The L5973D 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 device uses an internal P-channel D-MOS transistor (with a typical Rdson of 250 mO) as
switching element to minimize the size of the external components. An internal oscillator fixes the switching frequency at 250 kHz.

Features:

  • 2.5 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
  • 250 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: changers, car battery, DC-DC converters
