MIC4680YM Description

Short technical summary and product information.

The MIC4680YM from Microchip Technology is a versatile step-down (buck) switch-mode voltage regulator. It offers an adjustable output voltage down to 1.25V and can provide up to 1.3A of continuous output current.

 

This regulator features a wide input voltage range of 4V to 34V and operates at a fixed 200kHz switching frequency, contributing to its high efficiency of up to 90%. The device includes internal frequency compensation for fast transient response and ease of use, requiring a minimum number of external components. Protection features include cycle-by-cycle current limiting and thermal shutdown.

 

The MIC4680YM is supplied in an 8-pin SOIC package, suitable for surface mount applications. Its operating junction temperature range is -40°C to +125°C. The regulator also boasts a low shutdown-mode standby current of less than 2µA.

 

This component is ideal for various applications including simple high-efficiency step-down regulators, on-card switching regulators, and as an efficient pre-regulator in power supply designs.
