MIC4576-5.0WT 产品详情

The MIC4576-3.3WT is a series of easy to use fixed and adjustable BiCMOS step-down (buck) switch-mode voltage regulators. The 200kHz MIC4576-3.3WT duplicates the pinout and function of the 52kHz LM2576. The higher switching frequency may allow up to a 2:1 reduction in output filter inductor size.

The MIC4576-3.3WT is available in 3.3V, and 5V fixed output versions or a 1.23V to 33V adjustable output version. Both versions are capable of driving a 3A load with excellent line and load regulation.

The feedback voltage is guaranteed to ±2% tolerance for adjustable versions, and the output voltage is guaranteed to ±3% for fixed versions, within specified voltages and load conditions. The oscillator frequency is guaranteed to ±10%.

In shutdown mode, the regulator draws less than 200µA standby current. The regulator performs cycle-by-cycle current limiting and thermal shutdown for protection under fault conditions.

This series of simple switch-mode regulators requires a minimum number of external components and can operate using a standard series of inductors. Frequency compensation is provided internally.

The MIC4576-3.3WT is available in TO-220 (T) and TO-263 (U) packages for the industrial temperature range.

Feature

  • Fixed 200kHz operation
  • 3.3V, 5V, and adjustable output versions
  • Voltage over specified line and load conditions:
    • Fixed version: ±3% max. output voltage
    • Adjustable version: ±2% max. feedback voltage
  • Guaranteed 3A switch current
  • Wide input voltage range: 4V to 36V
  • Wide output voltage range: 1.23V to 33V
  • Requires minimum external components
  • < 200µA typical shutdown mode
  • 75% efficiency (adjustable version > 75% typical)
  • Standard inductors are 25% of typical LM2576 values
  • Thermal shutdown
  • Overcurrent protection
  • 100% electrical thermal limit burn-in
