Product Overview

The LM2594M-5.0 is a fixed output SIMPLE SWITCHER step down regulator in 8 pin SOIC package. This regulator is a monolithic integrated circuit that provides all active functions for a step down (buck) switching regulator. Requiring minimum number of external components, this regulator is simple to use and features internal frequency compensation, fixed frequency oscillator and improved line and load regulation specifications. A standard series of inductors (both through hole and surface mount types) are optimized for use with LM2594 step down regulator. This feature greatly simplifies the design of switch mode power supplies. Other features include an ensured ±4% tolerance on output voltage under all conditions of input voltage and output load conditions and ±15% on oscillator frequency. Self protection features include a two stage frequency reducing current limit for output switch and over temperature shut down for complete protection under fault conditions.
  • Fixed output voltage is 5V
  • 0.5A output current
  • Input voltage range from 4.5V to 40V
  • Requires only 4 external components
  • 150KHz fixed frequency internal oscillator
  • TTL shutdown capability
  • 85µA typical standby current
  • High efficiency up to 82%
  • Operating temperature range -40°C to 125°C
  • Low power standby mode
This 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 MOS gates.
