This non-isolated buck converter provides a fixed output of 14V at 130mA for BMS applications. It operates over an input voltage range of 18Vdc – 144Vdc after a startup greater than 23V. Operating in Discontinuous Conduction Mode (DCM), this converter utilizes the UCC28730 controller, which is referenced to the switch node. It offers high efficiency and low cost in a compact form factor.
