For End Products
- DC to DC Converter
- Distributed Control System
- Power Supplies
Description
- Circuit shows a 5V, 1A SEPIC converter designed to operate from a 12V battery. The bias supply on VIN and DRV limits the voltage to about 4V maximum at start-up, limiting the amount of quiescent power lost and maintaining a high efficiency
