Produktbeschreibung

The LM2574M-5.0 is a SIMPLE SWITCHER® 0.5A Step-down Voltage Regulator, monolithic integrated circuit provides all the active functions for a step-down (buck) switching regulator, capable of driving a 0.5A load with excellent line and load regulation. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed-frequency oscillator. The LM2574M-5.0 offers a high-efficiency replacement for popular three-terminal linear regulators. Because of its high efficiency, the copper traces on the printed circuit board are normally the only heat sinking needed. A standard series of inductors optimized for use with the LM2574 is available from several different manufacturers. This feature greatly simplifies the design of switch-mode power supplies.
  • Requires only 4 external components
  • 52kHz Fixed frequency internal oscillator
  • TTL shutdown capability, low power standby mode
  • High efficiency
  • Uses readily available standard inductors
  • Thermal shutdown and current limit protection

Hinweise

Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
