Features & Applications
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
