Features & Applications

The LM2575-12WT is a high-efficiency Step-Down Buck Regulator with an output voltage of 12 V and 1 A, available in TO-220-5 Package.

It is simple to use because they require a minimum number of external components and include internal frequency compensation and a fixed frequency oscillator.

Features:

  • 3.3V, 5V, 12V, and adjustable output versions
  • Voltage over specified line and load conditions:
    • Fixed version: ±3% max. output voltage
    • Adjustable version: ±2% max. feedback voltage
  • Guaranteed 1A output current
  • Wide input voltage range: 4V to 40V
  • Wide output voltage range: 1.23V to 37V
  • Requires only 4 external components
  • 52kHz fixed frequency internal oscillator
  • Low power standby mode IQ typically < 200µA
  • 80% efficiency (adjustable version typically > 80%)
  • Uses readily available standard inductors
  • Thermal shutdown and current limit protection
  • 100% electrical thermal limit burn-in

Applications:

  • Simple high-efficiency step-down (buck) regulator
  • Efficient pre-regulator for linear regulators
  • On-card switching regulators
  • Positive to negative converter (buck-boost)
  • Negative boost converter
  • Isolated flyback converter using minimum external components
