Product Overview

The LM2574HVN-15/NOPB is a SIMPLE SWITCHER step down (buck) voltage regulator with fixed output in 8 pin DIP package. It provides all active functions required for step down (buck) switching regulator. This simple to use regulator includes internal frequency compensation and fixed frequency oscillator. The LM2574HV offers high efficiency replacement for popular three terminal linear regulators. It substantially reduces size of heat sink and in many cases, heat sink is not required. A standard series of inductors optimized for use with LM2574HV are available from several different manufacturers. This feature greatly simplifies the design of switch mode power supplies. This regulator also includes specified ±4% tolerance on output voltage within specified input voltages and output load conditions and ±10% on oscillator frequency. External shutdown function features 50µA (typical) standby current.
  • Fixed output voltage of 15V
  • Output current of 0.5A
  • Wide input voltage range from 4V to 60V
  • 52KHz fixed frequency internal oscillator
  • TTL shutdown capability and low power standby mode
  • Thermal shutdown and current limit protection
  • Excellent line and load regulation
  • Operating temperature range from -40°C to 125°C
  • Requires only four external components
This device has limited built-in ESD protection. The leads should be shorted or device should be placed in conductive foam during storage or handling to prevent electrostatic damage to MOS gates.
