Beschreibung
Demonstration circuit 1891A is a 2-phase high efficiency nonisolated SEPIC (single ended primary inductor converter) converter featuring the LTC®3862-2 switching Controller. The DC1891A converts a 6V to 60V input to a 12V output and provides 6A of output current. The converter operates at 300kHz (600kHz output ripple) with efficiency around 90%. With a proper amount of airflow, the DC1891A converter can generate over 6A of output current. The DC1891A can be easily modified to generate output voltages in the range from 0.8V to 48V.
Also, the DC1891A can be optimized for specific input voltages. The narrowing of input voltage range can increase the converter’s efficiency. Therefore, a narrow input voltage range is more desirable.
The LTC3862-2 can be synchronized to an external clock of up to 400kHz. Please refer to LTC3862-2 data sheet for design details and applications information.
