Demonstration circuit 1206 is a step-down converter, using the LTC3568 monolithic synchronous buck regulator. The DC1206 has an input voltage range of 2.25V to 5.5V, and is capable of delivering up to 1.8A of output current at a minimum input voltage of 2.25V. The output voltage of the DC1206 can be set as low as 0.8V, the reference voltage of the LTC3568. At low load currents, the DC1206 can operate in either noise sensitive applications, due to the capability of the LTC3568 to operate in pulse-skipping mode, or in high efficiency applications, because the LTC3568 can also operate in Burst-Mode®. During Burst-Mode® operation, the output ripple voltage is still low – less than 30 mV – due to the improvements made in the design of the LTC3568.
