1A 200kHz SuperSwitcher™

Buck Regulator

General Description

Features

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

adjustable output voltage step-down (buck) switch-mode

voltage regulator. The 200kHz MIC4680 achieves up to

1.3A of continuous output current over a wide input range

in a 8-pin SOIC.

• SOIC-8 package with up to 1.3A output current

• All surface mount solution

• Only 4 external components required

• Fixed 200kHz operation

• 3.3V, 5V, and adjustable output versions

• Internally compensated with fast transient response

• Wide 4V to 34V operating input voltage range

• Less than 2µA typical shutdown-mode current

• Up to 90% efficiency

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 2µA of

standby current.

• Thermal shutdown

• Overcurrent protection

The MIC4680 SuperSwitcher™ regulator requires a mini-

mum 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.

Applications

• Simple 1A high-efficiency step-down (buck) regulator

• Replacement of TO-220 and TO-263 designs

• Efficient pre-regulator (5V to 2.5V, 12V to 3.3V, etc.)

• On-card switching regulators

• Positive-to-negative converter (inverting buck-boost)

• Simple battery charger

The MIC4680 is available in the 8-pin SOIC with a

–40°C to +125°C junction temperature range.

• Negative boost converter

• Higher output current regulator using external FET
