General Description

The MIC4680 SuperSwitcher™ is an easy-to-use fixed

or adjustable output voltage step-down (buck)

switch-mode voltage regulator. The 200 kHz MIC4680

achieves up to 1.3A of continuous output current over

a wide input range in a 8-lead SOIC.

The MIC4680 is available in 3.3V and 5V fixed output

versions or adjustable output down to 1.25V.

The MIC4680 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 2 μA

of standby current.

The MIC4680 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.
