High voltage buck converter reference design for BMS applications
Description
This non-isolated buck converter provides a fixed output of 14 V at 130 mA for BMS applications. It operates over an input voltage range of 18 Vdc – 144 Vdc after a startup greater than 23 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.
Features
- Unique floating controller ground reference allows operation at high input voltage (144 V)Achieves an efficiency of between 79% - 86% (30-V to 120-V input: 130-mA output)Low component count and small sizeUtilizes a single standard inductor (no transformer required)
