DC1043A-B

製品概要

Demonstration circuit DC1043A-B features three LTM4601EV high efficiency, high density switch mode step-down power modules in parallel (the LTM4601-1 can be substituted for the slave devices). The input voltage range is from 5.0V to 20V. The output voltage is programmable from 0.6V to 3.3V; refer to step down ratio curve in the LTM4601 datasheet. The rated load current is 30A, while de-rating is necessary for certain V_IN, V_OUT, and thermal conditions. Master module U1 provides differential remote sensing to accurately regulate output voltage independent of load current. Integrated input and output filters enable a simple PCB layout. Only bulk input and output capacitors are needed externally.
