Product Details

Demonstration circuit 1453A features the LTM4619EV, a 4.5V to 28V input, high efficiency, high density, dual 4A step-down power module with 1.8V and 3.3V output voltages. Derating is necessary for certain VIN, VOUT, and thermal conditions. The two outputs are interleaved with 180° phase to minimize the input ripple and reduce the input capacitors. A minimum design only requires the bulk input and output capacitors and voltage setting resistors. The LTM4619EV features output voltage tracking, power good indicator, RUN pin control, clock synchronization and soft-start programming. Protection features include foldback current limiting and overvoltage protection. Burst Mode® operation or pulse skipping mode can be selected for better light load efficiency.
