The MIC4680-2.5BM SuperSwitcher™ is an easy-to-use fixed or adjustable output voltage step-down (buck) switch-mode voltage regulator. The 200kHz MIC4680-2.5BM achieves up to 1.3A of continuous output current over a wide input range in a 8-pin SOIC.
The MIC4680-2.5BM is available in 3.3V and 5V fixed output versions or adjustable output down to 1.25V.
The MIC4680-2.5BM 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 2µA of standby current.
The MIC4680-2.5BM SuperSwitcher™ 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 MIC4680-2.5BM is available in the 8-pin SOIC with a -40°C to +125°C junction temperature range.
