Description

The TPS54331 is a non-synchronous buck converter that integrates a low RDS(on) high side MOSFET and is designed to provide up to a 3A output from an input voltage source of 3.5 V to 28 V. This application note explains the procedure of converting a simple buck converter into a CC/CV charger with low component count for charging a SMF Lead Acid Battery. This concept can be extended to multiple parts in the same family.
