Introduction High Efficiency 2-Phase Converter Produces 12V
The LTC3890 (dual outputs) and LTC3891 (single at 25A
output) step-down DC/DC controllers directly accept Figure 1 shows the LTC3890 in a 2-phase single output
inputs from 4V to 60V. This wide input range covers step-down converter configuration that delivers 25A
input voltages for single or double battery automotive at 12V, which can be scaled up to 75A by adding more
