Description

This non-isolated buck converter provides a fixed output of 12 V at 400 mA for BMS applications. It operates over an input voltage range of 50 V_DC–150 V_DC after a start-up greater than 40 V. 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.
