Description

This battery charger reference design uses a SEPIC topology. The input voltage range is 17V to 21V and is designed for a maximum load current of 600mA. The output voltage can range from 13V to 41V and is inversely proportional to the load current (CV charging method).

Features
  • CV charge method
  • Supports ultra-wide battery voltage range
  • Adjustable maximum load current
  • Low cost solutioin
  • Low input and output ripple
  • Design has been built and tested
