Description
The BR301 is non-isolated step down type DC/DC
converter module. The single module includes: a control IC,
inductor, ceramic capacitor, and standoff pins. This provides a
complete DC / DC converter solution, requiring few external
components. It can be configured easily, reducing overall
design time, allowing reuse of designs, and saving space on
the application PCB.
Applications:
⢠Factory Automation
⢠Communication devices
⢠Consumer electronics
⢠Other low power conversion
