    Products Detail

    The LM2575 series is a step-down (buck) switching regulator capable of driving 1A load with excellent line and load regulation. It requires minimal external components and includes internal frequency compensation and a fixed-frequency oscillator. Available in fixed (3.3V, 5V, 12V) and adjustable (1.23V to 37V) output versions. Features include high efficiency (typically >80% for adjustable), low power standby mode (<200µA), thermal shutdown, current limit protection, and compatibility with standard inductors. It serves as a high-efficiency replacement for linear regulators, reducing heat sink requirements.

    Key Features

    • Fixed output versions: 3.3V, 5V, 12V
    • Adjustable output: 1.23V to 37V
    • Voltage tolerance: Fixed ±3%, Adjustable ±2%
    • Guaranteed 1A output current
    • Input voltage range: 4V to 40V
    • Requires only 4 external components
    • 52kHz fixed frequency oscillator
    • Low power standby mode IQ typically <200µA
    • Efficiency: 80% (adjustable typically >80%)
    • Uses standard inductors
    • Thermal shutdown and current limit protection
    • 100% thermal limit burn-in

    Application scenarios

    • Simple high-efficiency step-down (buck) regulator
    • Efficient pre-regulator for linear regulators
    • On-card switching regulators
    • Positive to negative converter (inverting Buck-Boost)
    • Isolated flyback converter
