The L5970D013TR is a step down monolithic power switching regulator capable to deliver up to 1 A at output voltages from 1.2 V to 35 V. The device uses an internal P-Channel D-MOS transistor (with a typical Rdson of 250mΩ) as switching element to minimize the size of the external components.

An internal oscillator fixes the switching frequency at 250 KHz. Having a minimum input voltage of 4.4 V only, it is particularly suitable for 5 V bus, available in all computer related applications. Pulse by pulse current limit with the internal frequency modulation offers an effective constant current short circuit protection.

Features:

  • Up to 1 A output current
  • Operating input voltage from 4.4 V to 36 V
  • 3.3 V / (±2%) reference voltage
  • Output voltage adjustable from 1.2 V to 35 V
  • Low dropout operation: 100% duty cycle
  • 250KHz 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
