4V to 18V (Cold Crank) Input to 12V Output 3mm Maximum Height All Ceramic SEPIC

4V to 18V (Cold Crank) Input to 12V Output 3mm Maximum Height All Ceramic SEPIC

12V buses are often derived from sources with a wide input voltage range. For instance, automotive solutions can have steady-state operating voltages as high as 18V and as low as 4V for cold-crank conditions. Figure 4 shows a simple, low cost and low profile (3mm) solution that avoids the high cost of using both a boost and buck converter and maintains 12V system power during cold crank conditions.
