L5973AD - 2A switch step down switching regulator

Description

The L5973AD 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 output voltage can be set from 1.235 V to 35 V.

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.
