Microchip, MIC4680-5.0YM-TR DC-DC Converter, 1-Channel

The Microchip MIC4680 1.3A buck regulator is an easy-to-use fixed or adjustable output voltage step-down (buck) switch-mode voltage regulator. It operates on 4V to 34V voltage range. 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.
