General Description
Features
The MIC4682 is an easy-to-use step-down (buck) switch-
Programmable output current limit
mode voltage regulator. It features a programmable
– 10% accuracy over temperature
current limit that allows 10% current limit accuracy over its
Wide 4V to 34V operating input voltage range
full operating temperature range. The precision current
Fixed 200kHz PWM operation
limit makes the MIC4682 ideal for constant-voltage
Power SOIC-8 package allows 2A continuous output
constant-current applications, such as simple battery
current
chargers. The precision current limit also gives designers
the ability to set the maximum output current below the
All surface mount solution
saturation current rating of the inductor. This allows the
Internally compensated
use of the smallest possible inductors for a given
Less than 1µA typical shutdown-mode current
application, saving valuable space and cost.
Thermal shutdown protection
The MIC4682 is a very robust device. Its 4V to 34V input
voltage range allows the MIC4682 to safely be used in
applications where voltage transients may be present.
Applications
Additional protection features include cycle-by-cycle
Battery chargers
current limiting and over-temperature shutdown. The
White LED drivers
MIC4682 is available in a thermally optimized power
SOIC-8 package that allows it to achieve 2A of continuous
Constant voltage constant current step-down
output current.
converters
The MIC4682 requires a minimum number of external
Simple step-down regulator with precise current limit
components and can operate using a standard series of
USB power supplies
inductors. Compensation is provided internally for fast
transient response and ease of use. The MIC4682 is
available in the 8-pin power SOIC with a –40°C to +125°C
junction temperature range.
