Product Overview

The LM2574-5.0YN is a Buck Regulator contains all of the active circuitry necessary to construct a step-down (buck) switching regulator and requires a minimum of external components. The LM2574 is available in 3.3 and 5V fixed output versions or an adjustable version with an output voltage range of 1.23 to 37V. Output voltage is guaranteed to ±4% for specified input and load conditions. It can supply 0.5A 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. An external shutdown connection selects operating or standby modes. Standby current is less than 200µA. Heat sinks are generally unnecessary due the regulator's high efficiency. It includes internal frequency compensation and an internal 52kHz fixed frequency oscillator guaranteed to ±10% of the frequency.
  • Thermal shutdown and current limit protection
  • Requires only 4 external components
  • Shutdown capability (standby mode)
  • High-efficiency
  • Uses standard inductors
