MIC4680

1A 200 kHz SuperSwitcher™ Buck Regulator

Features

General Description

• SOIC-8 Package with Up to 1.3A Output Current

• All Surface Mount Solution

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.

• Only Four External Components Required

• Fixed 200 kHz Operation

• 3.3V, 5V, and Adjustable Output Versions

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

versions or adjustable output down to 1.25V.

• Internally Compensated with Fast Transient

Response

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.

• Wide 4V to 34V Operating Input Voltage Range

• Less than 2 µA Typical Shutdown Mode Current

• Up to 90% Efficiency

• Thermal Shutdown

• Overcurrent Protection

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.

Applications

• Simple 1A High-Efficiency Step-Down Regulator

• Replacement TO-220 and TO-263 Designs

• Efficient Pre-Regulator (5V to 2.5V, 12V to 3.3V,

etc.)

Package Type

• On-Card Switching Regulators

• Positive-to-Negative Converter (Inverting

Buck-Boost)
