LM2575HV Datasheet Simple Switcher 1a Step-down Voltage Regulator

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM1575/LM2575/LM2575HV Series SIMPLE SWITCHER 1A Step-Down Voltage Regulator LM1575/LM2575/LM2575HV SIMPLE SWITCHER® 1A Step-Down Voltage Regulator.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General 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.

Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed-frequency oscillator.

Key Features

  • include a guaranteed ±4% tolerance on output voltage within specified input voltages and output load conditions, and ±10% on the oscillator frequency. External shutdown is included, featuring 50 μA (typical) standby current. The output switch includes cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions. Features.
  • 3.3V, 5V, 12V, 15V, and adjustable output versions.
  • Adjustable version output voltage range, 1.23V to 37V (57V for HV vers.
