Description
The BR300 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
