This small SEPIC converter accepts a wide input voltage range, 4V...40V, from automotive battery and supports the cranking phase. Vout is kept stable thank to the SEPIC topology. During cranking the input voltage can reach vaules as low as 4V. Extensive testing with a source generator have been performed.
Features
- Supports the highly demanding cranking profile by stable 12Vout@2.5A
- Good efficiency from 9V to 24Vin in the range of 88%...91%
- Low noise generation thank to a mix of electrolytic capacitor, ferrite bead, and ceramic filter
