    產(chǎn)品信息

    The LM2594 series of Buck Switching Regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulation.
    Requiring a minimum number of external components, these Buck Switching Regulators are simple to use and include internal frequency compensation, and a fixed-frequency oscillator.
    The LM2594 series operates at a switching frequency of 150 kHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Available in a standard 8-lead PDIP package and 8-lead SOIC surface mount package.
    A standard series of inductors are available from several different manufacturers optimized for use with the LM2594 series. This feature greatly simplifies the design of switch-mode power supplies.
    Other features include a guaranteed +/-4% tolerance on output voltage under specified input voltage and output load conditions, and +/-15% on the oscillator frequency. External shutdown is included, featuring typically 80 μA standby current. Self protection features include a two stage frequency reducing current limit for the output switch and an over temperature shutdown for complete protection under fault conditions. See LM2596 for 3.0A and LM2595 for 1.0A.
    • Adjustable output voltage range, 1.2V to 37V +/-4% max over line and load
    • Available in TO-220 and D2PAK packages
    • Guaranteed 0.5A output load current
    • Input voltage range up to 40V
    • Excellent line and load regulation specifications
    • 150 kHz fixed frequency internal oscillator
    • TTL shutdown capability
    • Low power standby mode, Iq typically 80 μA
    • Uses readily available standard inductors
    • Thermal shutdown and current limit
