Features & Applications
The MIC4680YM TR SuperSwitcher™ is an easy-to-use fixed or adjustable output voltage step-down (buck) switch-mode voltage regulator. The 200 kHz MIC4680 achieves up to 1.3 A of continuous output current over a wide input range in a 8-lead SOP (small outline package).

The MIC4680 has an input voltage range of 4 V to 34 V, with excellent line, load, and transient response. The regulator performs cycle-by-cycle current limiting and thermal shutdown for protection under fault conditions. In shutdown mode, the regulator draws less than 2 µA of standby current.

Features:

  • SO-8 package with up to 1.3 A output current
  • All surface mount solution
  • Only 4 external components required
  • Fixed 200 kHz operation
  • 3.3 V, 5 V, and adjustable output versions
  • Internally compensated with fast transient response
  • Wide 4 V to 34 V operating input voltage range
  • Less than 2 µA typical shutdown-mode current
  • Up to 90% efficiency
  • Thermal shutdown
  • Overcurrent protection

Applications:

  • Simple 1 A high-efficiency step-down (buck) regulator
  • Replacement of TO-220 and TO-263 designs
  • Efficient preregulator (5 V to 2.5 V, 12 V to 3.3 V, etc.)
  • On-card switching regulators
  • Positive-to-negative converter (inverting buck-boost)
  • Simple battery charger
  • Negative boost converter
  • Higher output current regulator using external FET
