Microchip Technology, Inc. Voltage Regulator MIC4680-5.0YM

The MIC4680 is a step-down (buck) voltage regulator designed for efficient power management, capable of delivering up to 1.3A of continuous output current. It operates within an input voltage range of 4V to 34V and is available in fixed output versions of 3.3V and 5V, as well as an adjustable output down to 1.25V. The device features a fixed operating frequency of 200kHz and is internally compensated for fast transient response, requiring only a minimal number of external components for operation. The MIC4680 includes essential protection features such as cycle-by-cycle current limiting and thermal shutdown, ensuring reliable performance under fault conditions. In shutdown mode, it consumes less than 2¬µA of standby current, making it suitable for battery-powered applications. The product is housed in an 8-pin SOIC package and operates over a wide junction temperature range of -40¬8C to +125¬8C. Its efficiency can reach up to 90%, making it a viable option for various applications, including on-card switching regulators and battery chargers.
