Description

The MIC4680YM is a 1A 200kHz Buck Regulator with an easy-to-use fixed or adjustable output voltage step-down (buck) switch-mode voltage regulator. The MIC4680 is available in 3.3 and 5V fixed output versions or adjustable output down to 1.25V. The SuperSwitcher™ regulator has an input voltage range of 4 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.
Only 4 external components required
Internally compensated with fast transient response
Up to 90% efficiency
Thermal shutdown
Over-current protection
