Fonctionnalités et applications

The L5972D is a step down monolithic power switching regulator with a minimum 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 output voltage can be set from 1.235 V to 35 V. 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 250kHz. Having a minimum input voltage of 4.4 V only, it is particularly suitable for 5V bus, available in all computer related applications.

Features:

  • 2 A internal switch
  • Operating input voltage from 4.4 V to 36 V
  • Output voltage adjustable from 1.235V to 35 V
  • Low dropout operation: 100% duty cycle
  • 250 kHz Internally fixed frequency
  • Voltage feedforward
  • Zero load current operation
  • Internal current limiting
  • 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
