2575T-12 Overview

Description

The LM2575 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, 15V, and an adjustable output version.

Key Features

  • Adjustable version output voltage range, 1.23V to 37V (57V for HV version) ± 4% max over line and load conditions
  • Guaranteed 1A output current
  • Wide input voltage range, 40V up to 60V for HV version
  • Requires only 4 external components n 52 kHz fixed frequency internal oscillator
  • TTL shutdown capability, low power standby mode
  • High efficiency
  • Uses readily available standard inductors
  • Thermal shutdown and current limit protection
  • P+ Product Enhancement t
