MIC4680 Data Sheet
1A 200kHz SuperSwitcherâ„¢
Buck Regulator General Description Features The MIC4680 SuperSwitcherâ„¢ is an easy-to-use fixed or
adjustable output voltage step-down (buck) switch-mode
voltage regulator. The 200kHz MIC4680 achieves up to
1.3A of continuous output current over a wide input range
in a 8-pin SOIC.
The MIC4680 is available in 3.3V and 5V fixed output
versions or adjustable output down to 1.25V.
The MIC4680 has an input voltage range of 4V to 34V,
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 2ÂµA of
The MIC4680 SuperSwitcherâ„¢ regulator requires a minimum number of external components and can operate
using a standard series of inductors and capacitors.
Frequency compensation is provided internally for fast
transient response and ease of use.
The MIC4680 is available in the 8-pin SOIC with a
â€“40Â°C to +125Â°C junction temperature range. SOIC-8 package with up to 1.3A output current
All surface mount solution
Only 4 external components required ...
