Features & Applications
The LM2574YN is easy to use fixed and adjustable switching voltage regulators. The LM2574 contains all of the active circuitry necessary to construct a stepdown (buck) switching regulator and requires a minimum of external components.

The LM2574 is available in 3.3 V, 5 V, and 12 V fixed output versions, or an adjustable version with an output voltage range of 1.23 V to 37 V. Output voltage is guaranteed to ±4% for specified input and load conditions.The LM2574 can supply 0.5 A while maintaining excellent line and load regulation. 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 V, 12 V, and Adjustable Output Versions
  • Adjustable Version Output 1.23 V to 37 V ±4% Max.
  • Guaranteed 0.5 A Output Current
  • Wide Input Voltage, up to 40 V
  • Thermal Shutdown and Current Limit Protection
  • Requires only 4 external Components.
  • Shutdown Capability (Standby Mode)
  • Low Power Standby Mode < 200 µA Typical
  • High Efficiency
  • 52 kHz Fixed Frequency Internal Oscillator
  • Uses Standard Inductors

Applications:

  • Simple High-efficiency Step-down (Buck) Regulator
  • Efficient Pre-Regulator for Linear Regulators
  • On-card Switching Regulators
  • Positive to Negative Converter (Buck-Boost)
