Demonstration circuit 1787A is a wide input voltage range SEPIC converter featuring the LT3759 controller. It converts a 2.8V~36V input to a 12V output, with 1A load current capability for VIN ≥ 4V. The converter operates at a 300 kHz nominal switching frequency, with 91% peak efficiency. The DC1787A can be easily modified to generate other output voltages, and can also be optimized for efficiency and size with narrower input voltage ranges.
