Product Summary
The MIC4680-5.OYM is an easy-to-use fixed or adjustable output voltage step-down (buck) switch-mode voltage regulator. The MIC4680-5.OYM achieves up to 1.3A of continuous output current over a wide input range in a 8-lead SOP (small outline package). The MIC4680-5.OYM is available in 3.3V and 5V fixed output versions or adjustable output down to 1.25V. The MIC4680-5.OYM 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 MIC4680-5.OYM 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.
