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

*The ripple measurement is made at both ends of the electrolytic capacitor CO (470 μF). For the capacitor CIN , a YXF type made by Rubycon for
switching power supplies, or equivalent, is recommended. For CO, a low impedance ZL type made by Rubycon for switching power supplies, or
equivalent, is recommended. In this case, a 470 μF electrolytic capacitor was connected at 10 mm trace length from the output terminal.

Typical application circuit example
• An input electrolytic capacitor, CIN , of approximately 220 μF should be connected to the input
side of the BR301. If the input voltage is stable, it is not required.
• An output capacitor, CO, either electrolytic of approximately 470 μF or ceramic of
approximately 30 μF should be connected to the output side of the BR301.
• For CIN , a YXF type made by Rubycon for switching power supplies or equivalent is
recommended.
• For CO , either a low impedance ZL type made by Rubycon, or three ceramic capacitors
connected in parallel (GRM31CR71E106KA12 made by Murata), for switching power
supplies or equivalent are recommended.
• Depending on PCB layout, output voltage ripple could be amplified. Please check the output
voltage ripple in the actual application.
