LM2575 Datasheet Step-down Switching Regulator

Manufacturer: onsemi

Overview: Regulator, Step-Down Switching, Adjustable Output Voltage, 1.0 A LM2575, NCV2575 The LM2575 series of regulators are monolithic integrated circuits ideally suited for easy and convenient design of a step−down switching regulator (buck converter). All circuits of this series are capable of driving a 1.0 A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5.0 V, 12 V, 15 V, and an adjustable output version. These regulators were designed to minimize the number of external components to simplify the power supply design. Standard series of inductors optimized for use with the LM2575 are offered by several different inductor manufacturers. Since the LM2575 converter is a switch−mode power supply, its efficiency is significantly higher in comparison with popular three−terminal linear regulators, especially with higher input voltages. In many cases, the power dissipated by the LM2575 regulator is so low, that no heatsink is required or its size could be reduced dramatically.

Key Features

  • include a guaranteed ±4% tolerance on output voltage within specified input voltages and output load conditions, and ±10% on the oscillator frequency (±2% over 0°C to 125°C). External shutdown is included, featuring 80 mA typical standby current. The output switch includes cycle.
  • by.
  • cycle current limiting, as well as thermal shutdown for full protection under fault conditions. Features.
  • 3.3 V, 5.0 V, 12 V, 15 V, and Adjustable Output Versions.
  • Adjustable Version.
