DC1215A is an demonstration board for step down converter, using the LTC3605 monolithic synchronous buck regulator. The DC1215A has a maximum input voltage 15V, and is capable of delivering up to 5A of output current at a minimum input voltage of 4V. The output voltage of the DC1215A can be set as low as 0.6V, the reference voltage of the LTC3605. At low load currents, the DC1215A operates in discontinuous mode, and during shutdown, it consumes less than 10uA of quiescent current. In continuous mode operation, the DC1215A is a high efficiency circuit of over 80%. The LTC3605 has phase lock circuits, allowing high current multiphase operation of several DC1215As in parallel. The DC1215A can also track another voltage with the LTC3605 track function. Because of the high switching frequency of the LTC3605, which is programmable up to 4 MHz, the DC1215A uses low profile surface mount components. All these features make the DC1215A an ideal circuit for many application.
