Features & Applications
The MIC4681YM SuperSwitcher™ is an easy-to-use step-down (buck) voltage-mode switching regulator. The 200kHz MIC4681 achieves over 1 A of continuous output current over a 4 V to 30 V input range in an 8-lead SOP package.
The MIC4681 features a high 2.1 A minimum current limit, making the device ideal for pulsed current applications such as GSM and TDMA cell phone battery chargers and power supplies. The MIC4681 sustains an output of 4.2 V/2 A within a typical GSM charging environment.
Features:
- SO-8 package with over 1 A continuous output current
- Capable of 2 A pulse charging for GSM applications
- All surface mount solution
- Only 4 external components required
- Fixed 200 kHz operation
- Adjustable output version
- Internally compensated with fast transient response
- Wide 4 V to 30 V operating input voltage range
- Less than 6 µA typical shutdown-mode current
- Up to 90% efficiency
- Thermal shutdown
- Overcurrent protection
Applications:
- Cellular phone battery charger
- Cellular phone power supply
- Simple 1 A continuous high-efficiency step-down (buck) regulator
- Replacement of a TO-220 and TO-263 designs
- Positive-to-negative converter (inverting buck-boost)
- Negative boost converter
- Higher output current regulator using external FET
