10W power led driver using LTC3112 DC converter

Using the LTC3112 fixed frequency synchronous buck-boost DC DC can be designed a very simple high efficiency, high power led driver electronic project .

The unique 4-switch, single inductor architecture of the LTC3112, provides low noise and seamless operation from input voltages above, below or equal to the output voltage.
With an input range of 2.7V to 15V, the LTC3112 is well suited for a wide variety of single or multiple cell battery, backup capacitor or wall adapter source applications .

The LTC3112 features selectable PWM or Burst Mode operation, an easily synchronized oscillator and output disconnect in shutdown. An output current monitor circuit allows the load current to be controlled or measured.

Other features of the LTC3112 DC DC converter include : circuit protection, soft-start, current limit and thermal shutdown.
As you can see in the circuit diagram this led driver project require few external electronic parts and can be used to drive high power leds that will require a maximum power up to 10 watt .
This Led driver electronic project require a input voltage range between 5 volt and 15 volt DC .
